Hi, it’s me again with a creative bug on 2025.31760, apple silicon M2.
I’m in the process of making my courses POP friendly and I’m used to compositing two noise TOPs and making this into a point cloud. old way was add SOP then instancing, I tried TOP to POP instead, in Position and Active mode.
With some of the operations in the comp TOP like Add, the fps rate started dropping, without the graphic memory filling up, then vulkan error and TD crash message
When it got interesting though is on launching it back, the interface started freaking out (missing text in the upper bar, then total chaos):
when opening the file my framerate dropped right away to something like 26 fps which is unusual for a “small” pointcloud of 1 million points. I could trace it down to the PointSprite MAT as the source and replacing this with a Line MAT made it work again.
We’ll have a look at the glitching but could you try this with the Line MAT and also let us know your OS version?
cheers
Markus
EDIT: the framerate was an issue due to the active channel bug mentioned in the next post.
there seems to be another bug where the points don’t update if the TOP texture’s alpha channel is >1 and used as the active channel.
Checking on this as well.
