Simon Edmondson Posted April 9, 2020 Posted April 9, 2020 Hello. I have mainly moved over to trying to use drawn and stop frame processes for projects. However, wanted to use volumetrics for a particular shot and returned to the fold for that. Unfortunately I'm having a lot of bother getting a consistent result. The shot was set up and tested using quick renders to check progress. All seemed well until I tried to render it out as a QT file. This is a screenshot of what was supposed to happen and this is the QT file. Clearly very different. When rendered as a single frame jpg it refuses to save the file, as apng it does not parse the file into readable form, this is a tga converted in PS. Here is an embedded copy of the prj Can anyone kindly point me to the errors of my ways ? thank you simon CNE 013 SH 000.mov Chickens 002.prj Quote
Hash Fellow robcat2075 Posted April 9, 2020 Hash Fellow Posted April 9, 2020 Hi Simon, I did a quick render to numbered jpgs and this is what i got. It looks a bit like your first screen capture. Tell me more about how this does or doesn't fit your expectations and we can advance from there. SimonTest000.mp4 Quote
Simon Edmondson Posted April 9, 2020 Author Posted April 9, 2020 Robert Thank you very much once again. It is as needed, except for the absence of volumetric lighting? At risk of sounding a bit pretentious, its the prelude to a 'Big Bang' sequence. Not the TV show but a sort of spoof on the moment of creation. The centre of the O is actually an egg. Its part of the Chicken and Egg project I've been working on. Is it the jpg format that is allowing it to work ? regards simon Quote
Hash Fellow robcat2075 Posted April 9, 2020 Hash Fellow Posted April 9, 2020 The white portion of your scene is the camera background color. If that is rendered to a format like PNG or TGA that includes a transparency channel, the background will be made transparent and probably appear as black depending on how it is used. JPG doesn't include transparency. Or you can turn "Alpha" buffer OFF in your render settings when rendering to TGA. The "Intensity" of the Spot light is only 50%. If i increase it to 200% the volumetric effect is more obvious. Quote
Guest Simon Edmondson Posted April 9, 2020 Posted April 9, 2020 Thank you Robert. Much appreciated. I've just tried to rend a jpg sequence and, every time, it pauses at the end of the first frame and flags up a message saying "Unable to save ..." I shall try a TGA sequence with the intensity turned up as you suggest. regards simon Quote
Hash Fellow robcat2075 Posted April 9, 2020 Hash Fellow Posted April 9, 2020 Perhaps just try saving to a different directory, with a simpler path. Are you on a Mac? Are you still using the OS that is compatible with A:M? Quote
Simon Edmondson Posted April 10, 2020 Author Posted April 10, 2020 Robert Thank you once again for your help. I got it to work as I wanted by, as you suggested, turning off the alpha and making the camera background black. Boosted the volumetric level to 1000% and rendered with 16 passes. Here is the result. While it works as a process. I think it needs some revision to make the H and W more legible in the sequence? I'm using V18g on the same Mac mini as previously, running OSX 10.85. regards simon 013.mov Quote
Hash Fellow robcat2075 Posted April 10, 2020 Hash Fellow Posted April 10, 2020 You can have the camera background color be any color you want if that is what you want to show through the holes that make the letters. It was the alpha channel effect that was making the background appear black.. Quote
Simon Edmondson Posted April 12, 2020 Author Posted April 12, 2020 Thank you Robert, much appreciated. This isn't the final version, it goes from colour to white light ( probably ) but it does give the idea. regards simon CnE 013.mov Quote
Hash Fellow robcat2075 Posted April 12, 2020 Hash Fellow Posted April 12, 2020 i re-compressed it to a quarter-size version that should load and play easier... SimonTest.mp4 Quote
