some questions about ocatane

[luoqiulin]

hi:
we decide to buy octane for maya,but i have some questions here

1,with demo version i can't batch render, if octane batch render will every fram load maya scene again?

2,my gtx970 has 4gb vram is that mean i can render 1920*1280 picture with 10million triangle poly and 30 4000*4000 textures? no more?

3, if i have two gtx970 without sli, will the vram be 8gb or still 4gb

thank you very much!!

Hi,

1) This depends on how you have the scene/options setup. Take a look at this manual page: http://render.otoy.com/manuals/Maya_2_0/?page_id=364

2) Be careful with triangle vs poly. Octane has a limit of around 19Million triangles, so about 10mil polygons. Geometry, render target and textures all take up VRAM. Also, your render target will increase in size if you have lots of passes enabled. 1 million triangles is roughly 130MB
A normal 1920x1280 render target takes about 50MB but with lots of passes enabled this might grow to 500MB or more.
A LDR (24 bit RGB) image will take up about 80MB - but octane has an out-of-core textures feature which means it can use textures from main memory, leaving more VRAM free for your geometry and render target. Or just plain allowing you to use a lot of very high res textures.

3) It will still be 4GB. Octane needs to copy the data to each GPU so it can render the scene. It can't reach over to other GPUs and share VRAM.
