Duke Posted September 26, 2006 Share Posted September 26, 2006 Hi all. I'm busy making a hoverboard for a project I'm doing. I applied a decal onto the top section of the board and gave it a quick render to see what it would look like. its far from finished but I wanted to see what the wood would look like. these strange markings have come up on the render is there someone that knows what could cause this. no matter what render settings or lighting, it appears everytime.

Dhar Posted September 26, 2006 Share Posted September 26, 2006 How about a wireframe to see how your splines are? Quote Link to comment Share on other sites More sharing options...
jpappas Posted September 26, 2006 Share Posted September 26, 2006 Hi, That hover board is casting an unusual looking shadow. Are you using Transparency or a CookieCutter texture map? -Jim Quote Link to comment Share on other sites More sharing options...
Duke Posted September 26, 2006 Author Share Posted September 26, 2006 Hi Dhar Here's a wireframe, I'm experiencing all kinds of wierd things with V13j I wonder if this is not a problem with it, when I make a new component for the hoverboard, i.e the motor that I'm doing now, I can't lasso the motor part, it wont select.. [attachmentid=20924] hope this makes sense. Leo Hi, That hover board is casting an unusual looking shadow. Are you using Transparency or a CookieCutter texture map? -Jim Jim I simply applied the decal as a planar, put the wood on the top and an aluminum on the bottom. also noticed the shadow.

Duke Posted September 26, 2006 Author Share Posted September 26, 2006 Hi Guys, am starting to get freaked out here. Its seems to just get worse... take a look at this. it looks like this thing has gone through a war. [attachmentid=20925] I'm stumped Leo Quote Link to comment Share on other sites More sharing options...
Admin Rodney Posted September 26, 2006 Admin Share Posted September 26, 2006 Duke, While its hard to tell as the image doesn't zoom in close enough it looks like you've got some illegal patches in there. That the areas where this appears to be the case also seems to be where the artifacts are present seems to indicate the problem. Can you post an extreme close up (in shaded wireframe) of the areas in question? If you can post the model (or part of it) even better yet.

KenH Posted September 26, 2006 Share Posted September 26, 2006 Maybe your normals are pointed the wrong way. Are you using porcelain? Can you post the model or try it in a new project/chor. It's quite nice weathering going on there...whatever the reason. PS Did you extrude the shape? Quote Link to comment Share on other sites More sharing options...
NancyGormezano Posted September 26, 2006 Share Posted September 26, 2006 I have noticed intermittent funnies with 13j - in particular with rotoscopes & front projection mapping - different from what you're doing - but may be related because: if I look at your example - it looks like the black artifacts on the skateboard have moved - indicating that the mapping has changed based on view angle - My results would vary randomly - never knew when it would happen - As soon as I got rid of the camera rotoscope being front projected on the ground plane (camera was at an extreme angle with respect to ground) - my random cases of really horrific artifacts went away. I haven't yet sent my example in to AMreports - as I was trying to get a simple case. Quote Link to comment Share on other sites More sharing options...
NancyGormezano Posted September 26, 2006 Share Posted September 26, 2006 Also - my question is: is there any reflectivity set for your skateboard ? - I also think my funnies were related to that as well ooops edit: hoverboard, not skateboard - pardon me.

Duke Posted September 26, 2006 Author Share Posted September 26, 2006 Hi Rodney All I can get right at this stage is a screen capture. (or if someone can tell me how to render a wireframe) heres as close as I can get: here's model as well. hopefully someone will see what the problem is. [attachmentid=20927] KenH I did use porcelain, and thanx to your post I remembered that I forgot to flip the normals although it didn't change much. I kinda like that weathered effect as well, but I have no idea how it happened. I traced out the shape of the board in topview and then extruded it downward. Nancy as for the skateboard thing, don't worry about it, (its not finished yet, I still gotta put the rockets on and some other stuff.) as far as I can tell there is no reflectivity set on the board.

Duke Posted September 27, 2006 Author Share Posted September 27, 2006 Hi all Thanx for your help and input, I have managed to sort things out. I found a few problems: 1: I applied porcelain and somehow forgot to flip the normals, thanx KenH for reminding me. (something I knew had to be done) 2: I found some problems with the splines. 3: The main reason for the artifacts that were appearing were, I had added an aluminium material in the whole body of the board and added the wood grain as a decal, somehow the aluminium caused the bumps and cracks. or at least that is what I think it was. to fix this I removed all of the materials and decals and started over. that seemed to fix it. Here is the end result. if there are any comments, I'd like to hear them. [attachmentid=20944] Quote Link to comment Share on other sites More sharing options...
jpappas Posted September 27, 2006 Share Posted September 27, 2006 Duke, You not only fixed the problems, but it looks like you also finished the rest of it -- a very cool looking model, nice! -Jim Quote Link to comment Share on other sites More sharing options...
Duke Posted September 27, 2006 Author Share Posted September 27, 2006 Thanx Jim. I am still going to do a little more with it. wanna get some flames out the rockets as well as the hover ring thingy's at the bottom, but I fixed things as I went on. must say, there's nothing that will teach you better than to struggle with it and figure it out. learned much about materials and decals with this one. thanx again for your comments.

Duke Posted September 28, 2006 Author Share Posted September 28, 2006 I finally finished the board. its my first attempt at making some thing that resembles flames, so comments will be appreciated.

UNGLAUBLICHUSA Posted September 28, 2006 Share Posted September 28, 2006 Glad to see that the problem was easily fixed. This kind of thread is great for others to follow along with to see where simple mistakes can frustrate the heck out of you! Very nice hoverboard.

Dhar Posted September 29, 2006 Share Posted September 29, 2006 That looks great. Now let's see it in ation Quote Link to comment Share on other sites More sharing options...
Duke Posted September 29, 2006 Author Share Posted September 29, 2006 Thanx UNGLAUBLICHUSA Frustrating it was, but like I said earlier, there's nothing like battling your ass of with something and getting it right in the end. Dhar, for the compliment, I will definitely let you see it fly, as soon as I'm done I'll post a preview. Leo Quote Link to comment Share on other sites More sharing options...
