how to stick a picture onto an object? I tried the rest positon sop, but it doesn't work for me.


I want to make a ground broken effect with camera projection method, and how to stick the image onto the ground? So when it cracks, the textures could move with the objects.

I found there was a posted topic about the renderman refrence object using “_pref”, but I cant find it, anyone can show me the link?

Many ways to do this. Here's a couple.

FSee how far up the chain you can create the uv's. Preferrably on the geoemtry just before you deform it.

You can lock down the effect in a SOP, apply uv's to the static locked geometry then using the second input of the Point SOP use $MAPU2 $MAPV2 and $MAPW2 for the Texture parms to transfer the uv's over to the deforming geometry.

Rest SOP generally works for procedural shaders, not texture maps.

how about projecting the image and then locking the uvtexture SOP?

“Rest SOP generally works for procedural shaders, not texture maps.”,I understand…thanks
