Dribble Large Render Large Textures

Post by clintonman » 08 Mar 2019, 01:28

Does anyone have a sample scene or instruction for making a scene that crashes the Dribble render? A few years ago it was mentioned that it crashed with high resolution renders, maybe combined with large textures but it wasn't clear to me.

Many factors can lead Dribble to crash : too many objects in the scene, too much vertices on a single object, too much pixels in the file to render.
To me, Dribble is at its best in animation : not heavy scenes, render at 1920x1080, textures files below 4000x4000 pixels.

I belive you can crash a Dribble render by adding a simple cube and clic the Quad_Divide tool several times until you get 393 216 faces.

Thanks, that did it.
1. Empty scene add cube
2. apply texture 4096 x 4096
3. subdivide cube until 393,218 faces - which took forever
4. render to screen ran ok
5. render to file 6000 x 6000 got the crash

The dribble code has a hidden option called "individual faces". It writes meshes as individual faces 1 by 1 with no shared vertices. That method would more than double the amount of memory used. The option is only accessible from a file inside the dribble folder called "default.drb". When I change a value in the file I can render the scene that caused a crash before.

I changed the text line about half way down from

Code: Select all

<individualfaces>1</individualfaces>
to

Code: Select all

<individualfaces>0</individualfaces>
The render took a long time, I walked away and when I returned I had a render and no crash.
