Max resolution of Tex3d TOP 2048x2048?

It seems like the maximum resolution of the tex3d TOP is 2048x2048? Is this a hardware limitation or a limitation of 3d textures in general?

thanks

For the longest time the max w/h/depth of a 3D Texture was only single constant in GL, so the w/h was limited to the max depth the hardware could do. Nvidia has added an extension to split query for the max w/h from the max depth. Not sure which GPUs or driver versions support it, but I’ve added support for it now. It’ll be in the next 16000+ series we post.

Great news! Thanks Malcolm!
