Hi Jimstar, thanks for your response.
What you see is happening on your side that is wrong?
A rather smooth scene (all alembic cache) slows to a crawl if I animate a texture via its projection or transform nodes.
Specifically scrubbing the timeline and DAG updates. This is specific to the Maya interface, not rendering.
What you expect to be happening so that it would be OK for you?
Speeds back up as I remove the animation curves from the shader's network.
Scubbing the timeline (i.e. DAG udpates) should be as smooth as a scene without texture animation.
If the same is happening for you in Standalone after exporting the scene (e.g. rendering slowdown) - you need to report it in the Standalone section.
Standalone doesn't have a viewport preview so this is irrelevant. Has nothing to do with rendering.
Clear step-by-step instruction of how I can reproduce it.
Setup any scene with a decent amount of geometry. Apply shaders, add file textures, add transform nodes, animate transform node values. Repeat to increase slow down.
The scene attached, where it is reproduceable.
If I find some time I'll setup a new scene that I can share.
