I have a scene where if I render it to an animation file (ogv) it renders differently in a few cases than if I render it to an image file (png).
To the image file it renders correctly using the texture appropriately. In the animation file it renders the color of the color node I have through the mix shader without observing the keyframe setting. I have the mix shader keyframed to only show 100% texture for the first several frames, and then mix in the color over the next several frames so it fades from textured to color-textured. Cycles is rendering the color always with 100% power to the animation file, but only to a handful of faces (they happen to be the top-most faces using the texture). They’ve all been UV unwrapped, and it’s always the same ones with the error. All of these faces are using the same texture material, and all of the UV faces are on the texture image. I have checkd and it’s not the result of normals. I have gone back in and re-assigned the texture. It renders correctly in any off-angle image as by pressing F12 or setting the viewport to render, but when viewed through the camera it renders the blue color instead of the texture.
Any ideas? This is the same scene in my other thread, and I can upload the .blend file if need be. It’s about 8 MB or so total.
