Your question is a little different from mrouioui because you’re going for image-based growth and mrouioui is looking for SOP growth.

I looked at your file and would recommend using a GLSL TOP rather than your first Render TOP. It would also be good to use a Feedback TOP. I’m not sure why TD isn’t detecting a dependency loop between /project1/glsl1 and /project1/texture.
