Path tracer clamps albedo to 1 on all bounces except the first. You can control the path tracer’s maximum ray depth with “Max ray depth in PT” on the Advanced tab, but it cannot go higher than 13 in this build. You can control the path tracer quality with “Max paths per sampler” on the Quality tab of the render node. Improved the adaptivity of the path tracer when using the Robust Adaptive Sampler. Improved the performance of the path tracer in lots of ways. Transparency (glossy/specular transmission) can be rendered with the path tracer. The path tracer option has moved to the Quality tab of the render node. The path tracer is ready for use in production.

Slightly increased the spatial resolution of cloud GI (relative to the number of voxels), taking advantage of the faster calculation in this version. This change comes at the expense of slightly reduced correctness which is unlikely to be noticeable in renders. Faster, Higher Quality Cloud GIĬloud GI calculation is now much faster in scenes with high micropoly detail and/or high ray detail multiplier. This is consistent with the behaviour of ImageWriterEXR. ImageWriterTIFF no longer prints anything when it succeeds, only when it fails. Please note that these images are not being properly generated in this build they are always black.īefore writing an image file, Terragen prints to stdout “Attempting to write image: ” followed by the filename. When tgSurfIndirectSpec is enabled, two new elements tgSurfIndirectSpecRefl and tgSurfIndirectSpecTrans are automatically output as well. When tgSurfIndirectDiff is enabled in a render layer, two new elements tgSurfIndirectDiffRefl and trSurfIndirectDiffTrans are automatically output as well. Temporary/automatic render output files (the ones named “tgout”) have a new filename format that includes the render time and the version of Terragen.

The render aborts if output folders don’t exist after attempting to create them. Output folders are verified and automatically created if necessary at the start of a render that outputs files. Render nodes automatically insert $.%04d.tif” respectively. That is, it only loads when it is needed by a preview or a render, and if the Heightfield Shader is disabled the loader won’t load. When loading projects with Geog Heightfield Load, it now respects the deferred loading policy which is used by other heightfield nodes. Glass Shader’s default scattering mode is “Subsurface scatter in all directions”. Improved the RTP’s rendering of surfaces with opacity less than 1. refractions and SSS) so they should work properly with the bump map behaviour mentioned above. This brings back the ability to use the “positive bump trick” to avoid sharp terminators on low-poly geometry.Ĭhanged how the ray origin is determined for transmission rays (e.g. Reverted the change from 4.4.40.frontier that prevented bump maps from displacing the shading position. The default scene has soft shadows enabled with 4 samples.įixed a mistake in the subdivision of displaceable surfaces when seen by rays at depth 3 or more.
