split expression sop

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

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.
