GPU Textures

This page provides information about the Textures rollout available under the Perf. tab when the production renderer is V-Ray GPU.

Overview

The Textures rollout is accessible through the Perf. tab of the Render Settings. These options give direct UI access to texture-related operations when the renderer is V-Ray GPU.

UI Path: ||Render Setup window|| > Performance tab > Textures rollout (Renderer set to V-Ray GPU)

Parameters

Mode – Determines how the resolution and size of textures are handled to optimize memory usage.

Full-size – Textures are loaded at their original size.
Compressed – Textures are loaded with compression to decrease GPU memory consumption. This texture mode sacrifices some texture quality to make the texture smaller (roughly ~75% reduction in memory usage). As a result, you need much less memory for textures, enabling renders of bigger scenes. Not all textures are compressed using this option, and exceptions are made based on the bitmap usage:

• If a bitmap is used for both normal/bump and color maps, as compression for normal maps is generally not good for color maps, and vice versa.
• Bitmaps that are used for displacement.
• Bitmaps that are used for lens effects.

Use System Memory for Textures – Lowers GPU memory usage significantly by offloading textures to system memory with little impact on performance.
