Hello everyone!

Just wanted to share a little thing i made inspired by this book .
The plan was to have blood drips (just like the cover) but i can't make mantaflow's viscosity work as i want it to, seems to be a bug? .
So.. here's an early render of it.. for now.. will update once/if i get things ...

The problem is here:


<kernel>:1320:20: error: use of undeclared identifier 'MBVH_NODES_PAGE_SIZE'
if (*nodeIndex >= MBVH_NODES_PAGE_SIZE) {


Going to check tomorrow what it is.


I should have fixed this problem: it was caused by a limitation on your GPU (i.e. the maximum size of ...

Hi guys, thanks for your quick responses.


2gb file size doesn't translate in GPU memory occupency linearly and tend to increase a lot.
Do you have some large high resolution textures ?
Can you update your GPU driver it help sometime.
Maybe a dev could be sharper answering here.


no textures at ...

Hi all,

i'm having an issue with OCL+path, it gives me an error saying "clBuildProgram". my scene renders as expected with CPU+path so i don't know what is going on. i thought it's the VRAM, but the scene is less than 2GB, my GPU has 6GB.

the blurred background really adds to the mood, nicely done!

happens to me too.
i just give it more time than usual and it actually renders, in both viewport and render view.
mine seems to "stop" at the end of the exporting phase but after the freeze it goes on as expected.
maybe we have heavier exports now due to the new features added since 2.3, not sure.
