Memory allocation failed- GPU-Beta error

Hi,

I am using NVDIA GTX 1080ti.

Getting this error while trying to render a character.

Memory Allocation failed (details: Function "RTresult _rtContextLaunch2D (RT context, unsigned int, RTsize, ) caught exception: Out of memory.

As the error message stated, you are "Out of memory" on the GPU. Perhaps you are loading in too many textures? There should be an option under render settings for restricting the max resolution to use for textures. And yes, we do plan on making this more automatic in the future, similar to how on the CPU you don't need to do this.

@Thiago Ize Hello, Some of my scene couldn't render with GPU but it still renders with CPU normal. I use all my texture with 4k resolution 3840 x 2160 for high resolution .. did I have to reduce texture to can render normal or what I should do in this case. and they are the same file .. I find little bit change of reflection between GPU and CPU and some texture couldn't be converted to tx .. any update will be coming soon .. .. what about fullback error when I choice CPU it also not works.. as I see performance from GPU is faster more than CPU with 1.5x time . sorry for my bad English .

Are you using Arnold displacement and subdivs? Trying keeping the height, but turning off subdivisions. I had the same problem and disabling subdivisions made the scene renderable again.

I decrease the subdivision level. That helped too.
