Hi, for anyone who has experience in nuke 3d, i got a problem when creating alpha, there’s a leak inside my alpha. Here’s i attach the screenshot (frame 27). Also i attach the obj and .nk file. So i import an .obj file , it’s just a simple sphere with a bit of surface modification (the sphere is dented on a spot) . Then i put a camera which is viewing from behind the dented area, then slowly rotating to finally revealing the dented area. I put a texture with a mask on that area (for the mask , i use 3d comp with mergemat node instead of using 2d compos, ). I only want to render that area , not the whole object, so i setup the scene to get only that part with alpha. Everything is ok except one thing, there’s imperfection of the alpha, kind like a leak on the alpha channel. The leak start to show at frame 17. The leak is showed up as the result from the mergemat node (as u can see in my screenshot , it’s grabbed from frame 27). I just don’t know what happen, if anyone here can help reviewing this. Did i miss something? I’ve found the temporary solution, by using stencil mode to get the inverse of the alpha. But i need to know what is wrong with my scene.
thanx
