Guest Posted July 31, 2017 Posted July 31, 2017 It appears your working on a private residence with siding. If it helps your concept, I can offer fairly convincing shingles via two BitMapPlus materials for colour and texture. Quote
Hash Fellow robcat2075 Posted August 1, 2017 Author Hash Fellow Posted August 1, 2017 Those look great Rodger! I've planned my view so that roof shingles aren't a visible part of the scene, but if I end up expanding my model to include a roof I may take you up on that. Thanks for the offer! btw, I hope we will be seeing a Rodger Reynolds entry in the Image contest! Quote

Hash Fellow robcat2075 Posted August 6, 2017 Author Hash Fellow Posted August 6, 2017 This is from my Show & Tell at yesterday's Live Answer Time. I've been repainting my house for a while and I noticed that after I scrape off the loose paint... ... it makes patchy shapes somewhat like the noise combiners we use to make wispy cloud cover. This is Fractal Sum, stretched horizontally... However, the Fractal Sum noise is a continuous range of shades from base color to peak color and the scraped paint on wood is either there or not there. ON or OFF. If i crank the "amplitude" of Fractal Sum above 100, more of the noise pattern is forced to clip at the peak color and I get more solid shapes... ... but that still leaves lots of gray in the inbetween areas. i really need all or nothing. It is possible to use these noise combiners materials for Displacement instead of Color. This is a flat patch with a noise material set to Displacement... But how about if I had two layers of patches instead of one? Here is a flat patch with a wood grain material made with the Spherical combiner... Now I've placed another flat patch just behind with a displacement material on it, far enough back so that only the very highest points poke out in front of the wood grained patch. This gets me the all or nothing look I wanted... Here's a two-tone version with two displacement layers behind the wood grain patch with one slightly more forward, to simulate yellow paint on top of white primer.The yellow layer noise is set to slightly lower Amplitude so its peak areas are slightly smaller than the white ones... I can also vary the Scale parameters of the noise materials to make the paint areas larger or longer Quote

Hash Fellow robcat2075 Posted August 29, 2017 Author Hash Fellow Posted August 29, 2017 Trying to think through some of the major contours involved in the head. This will not be accurate enough to just draw over in A:M and after I start splining I'll find that much of it is mistaken, but it's a starting point. Quote
Hash Fellow robcat2075 Posted August 29, 2017 Author Hash Fellow Posted August 29, 2017 My typical starting gambit is to minimally spline the profile off the rotoscope, then stick some eyeballs in. I know that anything I make after this has to be outside the eye balls... ...and i can use the surface of the eyeballs to place the eyelid opening. Easy to do with Snap-to-surface. Quote
Hash Fellow robcat2075 Posted August 30, 2017 Author Hash Fellow Posted August 30, 2017 I do the simple shapes first, for which I have some confidence about how many CPs they need... then I start extending splines from them to stitch them together... This first pass is looking disappointingly flattish. I have to keep telling myself that this isn't final. I can modify and respline it later once I have the whole general shape to appraise. Quote
harunw Posted August 31, 2017 Posted August 31, 2017 wow, this i think will make an excellent face modeling tutorial.i really like the first step you did, which was to sketch out the major spline contours...i don't remember seeing this mentioned in other face tutorials, but it's a very useful step i think... modeling has always been somewhat of a mystery to me, esp. figuring out where the splines ought to go... thanks for sharing...can't wait to see more....

Hash Fellow robcat2075 Posted September 3, 2017 Author Hash Fellow Posted September 3, 2017 Extending out the easier parts like the back of the skull I've tried to make the splines arrive at hole with as many CPs as the ear i will build to attach there I've noticed Pixar is doing very simple ears, basically a dish with no ear hole. i will try that. Putting the ear right up to the head makes it hard to find the splines to connect... ...so I will temporarily move it to the side and extrude out some extra spline to draw across and match up to CPs on the head... Even though both rings had 8 CPs, they don't necessarily match up exactly so some become hooks. Once I had the connections made, I deleted the ring that made the hole on the head since it would be superflous after I moved the ear back towards the head. I also resplined the inside of the ear to eliminate the lathed hole. Quote

Hash Fellow robcat2075 Posted October 31, 2017 Author Hash Fellow Posted October 31, 2017 As time was running out I decided to try helmet hair instead of particle hair. I started by using "snap to surface" to draw a spline where the part in the hair would go and then extruded that up and across the head one section at a time to make "the big flip." Then I did that again in the other direction to do the small side of the part. I didn't worry about the back too much since that wasn't going to show in my still image. Turns out, I do my hair pretty much the same way our President does his! (click to animate) Quote
largento Posted October 31, 2017 Posted October 31, 2017 I think I've finally figured out how Trump's hair looks like that. He obviously combs it back on the sides, but the magic trick is that he combs the hair from his part across the top of his head (from his left to right). Then, he has a combover from the back that is combed forward, over the hair on the top of his head at an angle and that hair is feathered the opposite direction and hidden under the part (on his left). I had to go back to younger photos, because his hair is so fine now, that it's hard to define. Quote
Hash Fellow robcat2075 Posted October 31, 2017 Author Hash Fellow Posted October 31, 2017 The T-shirt is a cloth simulation. I started with the most basic mesh I could spline to approximately form it to the character, then I used the SplitPatch plugin to subdivide it for cloth. There were several cycles of that where I'd run a simulation, decide it was too tight or too lose in places and go back to the low-spline version to make alterations, subdivide and test again. Since the shirt was made in a T-pose, the character needs to start out that way, too. I also made a pose slider for the character to squish him so that none of him was touching the cloth on the first frame. This GIF shows the complete simulation starting from the T-pose, expanding the body, and then moving into position for the planned image (click to animate) 4 Quote
Admin Rodney Posted November 1, 2017 Admin Posted November 1, 2017 That is a great demonstration of how it's done. Quote
Hash Fellow robcat2075 Posted November 24, 2017 Author Hash Fellow Posted November 24, 2017 I didn't get around to painting paint splotches on the clothes but I made some preparations for it. Pants are typically an awkward shape to apply a decal to. On this character the pants are just a series of spline rings, up one leg, across the hips and down the other leg.I made a pose that unfolds them into a simple cylinder that is easy to decal. It also rotates the whole set so that the seam at the back of the cylinder decal lands on the inseam of the pants, where I least need to paint.With this one decal on the whole shape it is easy to take the image back to a paint program and add my paint splotches. The temporary checkerboard pattern makes it easy to see which part of the 2D decal ends up on which part of the 3D shape. (click to animate) 1 Quote

The hints to the scene being part of a much larger world makes us believers that there really is a larger world there. My first thought was to use a dome with a 360° panorama on it but it's quite difficult to create such an image of high enough resolution so that you don't see pixels when you peer at just a small portion of it in the window reflections.

Hash Fellow robcat2075 Posted March 6, 2018 Author Hash Fellow Posted March 6, 2018 Initially, I put just numbers on the cards so it would be easier to be sure which one I was seeing in each window. Then I swapped in the proper images and fine tuned the placement. Quote
Hash Fellow robcat2075 Posted March 9, 2018 Author Hash Fellow Posted March 9, 2018 Because I don't like to paint in the Sun I envisioned this as a shady-side-of-the-house scene using Ambient Occlusion instead of directional lights.This is what the AO defaults do with Ambient Illumination and Occlusion set to 100% AO casts light from all directions but the Ground Plane is so large that it blocks all the light from below the horizon. That works well for most purposes but for something viewed from below it makes for some very dark surfaces facing the camera. In real life there is substantial light bounced up from the ground.To experiment, I progressively reduced the size of the Ground, to allow more light from below to reach the objects. You have to reduce it quite a bit to get a noticeable change. This is with 50% of the original dimensions... 20% 10%... No Ground Plane at all... The 20% version was about right for illumination levels but I began to get unhappy with the uniform grayness of it all. That led me to experimenting with Global Illumination, which I will show some tests of in the next post. 1 Quote
Admin Rodney Posted March 9, 2018 Admin Posted March 9, 2018 Enjoying your breakdown of how you put your entry together. Excellent breakdown of AO and how the size of ground plane effects the scene. I can see I need to experiment with reflected AO like that. Quote

Hash Fellow robcat2075 Posted March 17, 2018 Author Hash Fellow Posted March 17, 2018 In my AO experiments I decided i didn't like the grayness of it.It is possible it is possible to set the "Ambiance Color" to something other than white for a bluish skylight or reddish sunset coloration.... However, I still wanted something less the-same-all-over. If we set Global Ambiance Type to "Image Based Lighting" we can use a bitmap to make the light different colors from different directions.Image based lighting has a "Mapping Type" setting. The simplest is "Latitude-Longitude" which basically stretches and wraps an image 360° onto an imaginary sphere around your universe. You don't see it in the background of your render, it just colors the global light.What follows are experiments with different images (seen on the left) and the lighting result (seen on the right) This uses a photo taken in my front yard facing away from the house...Similar but curves adjusted in Photoshop to make it lighter... Added sky at top and painted in some "dirt" color for the ground The previous one was i the ball park but too green and still too dark so i reduced the saturation in Photoshop, painted out some of the green and did another curve adjustment to overall brighten it. I regarded this as satisfactory. The Image Based Lighting doesn't make a dramatically different result on the flat surfaces of the house but I like how the slight variations on the round shapes of the character create a Subsurface Scattering appearance even though the skin is just a default A:M surface.These IBL renders were done with no Ground plane. The light or lack of it from below was controlled by painting black at the bottom of the IBL image. Quote
