This group of attributes can be added to Substance textures textures to control the internal bitmap storage when rendered with V-Ray. Note that this feature depends largely on the ability of the Substance engine itself to provide the data with the required precision. This extra attribute is added only using scripting.
Override texture format– When enabled, you can specify the internal texture storage format when rendered with V-Ray.
Texture format – Specifies the internal texture storage format:
8-bit RGBA – The texture is stored with 8 bits per red, green, blue and alpha channels (32 bits per texel). 32-bit float – The texture is stored with 32-bit floating point values for the red, green, blue and alpha channels (128 bits per texel). 8-bit RGBE – The texture is stored in "real pixel" format with 8 bits for red, green and blue components and an 8 bit exponent for representing high dynamic range values. Alpha values are not stored in this format.
