chovasie Posted November 24, 2011 Share Posted November 24, 2011 Hi everyone! I started working on vopSop operator that will help me separate facial expressions. I use this method in maya with blendShape node where i use normalized textures from skinWeights to split my expressions. I want to make something like that in H using vopSop so i can make digital asset of it and use it when i need it... I managed to make it work with paintSop as input. Works perfect for me and do what i want it to do. But now i want to change input not to be from PaintSop, i want file texture instead. I tried to copy Cd values to verices and use that as input for color but it's not accurate. from some reason H use some average value for vertex Cd value. I need it more acurate like now from paintSop. i will attach my scene and all files here so if you have time and will take a look. It would be great if you can help me with this but not to change my solution completely. I would like to make this work if it's possible.. Thanx splitExpressionSop.rar Quote Link to comment Share on other sites More sharing options...
edward Posted November 24, 2011 Share Posted November 24, 2011 You should use a Texture VOP inside (promote the filename parameter) and do it that way instead? Quote Link to comment Share on other sites More sharing options...
Div Posted November 25, 2011 Share Posted November 25, 2011 Use a color map vop, the texture vop is not available inside a vopsop Quote Link to comment Share on other sites More sharing options...
chovasie Posted November 25, 2011 Author Share Posted November 25, 2011 (edited) Use a color map vop, the texture vop is not available inside a vopsop If i got you right you suggesting using color in vopSop. I tried to load texture in COP, than import cd attr in vopSop and use op:/img to point to texture... Houdini transfer Cd values to vertices over color sop but as i said i don't get exact values from texture on that CV. Houdini averages color value and transfer that value to vertex. Like that i don't get nearly precise as i need... When i try to add 2 shapes that i get from vopSop. I don't get same shape that i started from. I'm not sure that i got you right. But if you think of that method i described above.. i tried that and does not work for me. Maybe i do something wrong but so far i didn't manage to make it work for me.
