TERRAGEN RELEASE NOTES 4.3.23 WINDOWS

IOR slider goes from 1 to 5 on Default Shader. Roughness sliders go up to 1.0 on Reflective Shader, Glass Shader and Default Shader. UI changes related to specular roughness: The renderer no longer supports per-channel (RGB) roughness which was previously allowed for direct highlights. Glass Shader and Default Shader force a minimum specular roughness of 0.005 for direct lights (but not other rays) so that highlights are more likely to be visible when the shader's roughness is smaller than that. This visibly shifts reflections at high roughness and glancing angles, but some shift should occur naturally anyway. It now biases microfacets towards the ray origin using a formula based on roughness and viewing angle, to approximate the view-dependent distribution. Ĭhanged the path tracer's distribution of glossy reflection rays to correct an incorrect sharpness at high roughness settings. 'Beckmann TG 2' is also available for backward compatibility. They only affected the Reflective Shader.ĭefault Shader and Reflective Shader have two new specular roughness models: 'GGX' and 'Beckmann TG 4.5'. If 'Invert (gloss map)' is enabled, the squaring occurs after the inversion.įixed some problems with GGX and Beckmann TG 4.5 that occurred at very small roughness values.

This improves compatibility with many third-party PBR shaders. This changes the roughness curve by squaring the values in the image. Added 'Remap ^2' option for the roughness image. Removed the gamma option for metalness image. Deprecated the gamma options for roughness image and displacement image.

TERRAGEN RELEASE NOTES 4.3.23 WINDOWS

Windows only: Fixed the installer error 'Setup has detected that the file 'vcredist_圆4.exe' changed since it was initially published.'

Windows only: Fixed a recent bug that prevented loading of files larger than 2 GiB. If Gather Project fails to copy assets to the destination folder, the error message includes the name of the first failing asset and a little bit more information on why it failed.įixed a bug which could cause crashes when preview images are generated for the Library. On all platforms, Gather Project detects files that would clash on a Windows target machine due to case-insensitive filenames, and renames the destination files to resolve the conflict. On Windows, fixed an error that occurred when gathering a project with multiple references to the same file with different upper/lower case spellings. Windows only: Fixed a bug which sometimes didn't clear the image when starting a new render. Windows only: Fixed a crash when scanning a folder for Library items. Please contact us for information.įixed a bug in the Geog Image Map Shader which first occurred in v4.5.įixed a bug in the Shader Array which first occurred in v4.5.įixed a bug in the population cache (.pop) file writer which would add an extra instance at the origin.įixed a crash when the Library tried to display a project file that had been deleted. Licenses for educational use are available.
