TERRAGEN BLUR IMAGE NODE UPGRADE

You can choose from 3 different methods to calculate subsurface scattering This can be used to render objects with subsurface scattering. Water Shader and Glass Shader "volume density" and "volume colour" can be used with the path tracer.Fixed a bug in the path tracer that sometimes made it impossible to finish or stop renders and previews.The number of soft shadow samples has much less impact on render times Faster path tracing with soft shadows: When path tracing, the sampling of direct lights uses fewer samples in bounced light.This is necessary to be physically correct and to avoid extremely bright samples after multiple bounces 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 Cloud 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. Before writing an image file, Terragen prints to stdout "Attempting to write image: " followed by the filename.Please note that these images are not being properly generated in this build they are always black 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.New variables can be used in rendered output filenames.

We may need another solution for this in future builds However, this also means we can't use the positive bump trick to avoid sharp terminators on low-poly geometry. Bump mapping doesn't affect shading position anymore because this was causing incorrect rendering of transparency.

Changed how bump mapping affects the shading position.

To work around this bug, the reflective shaders do nothing when hit by camera rays in the GI prepass

Worked around a bug which can cause large amounts of noise in the atmosphere GI cache if reflective shaders are visible to the camera in the GI prepass.

The fix makes distant vegetation render more correctly

Fixed a bug with the ray bias in shadow rays originating far from the camera.

Corrected some flaws with motion blur when the pixel sampler is adaptive, by reverting to a random sampling strategy in this case.

The "Robust adaptive sampler" checkbox in the Render Pixel Sampler has been replaced by two radio buttons: "Legacy adaptive sampler" and "Robust adaptive sampler".

Both of these changes provide a better ratio of image quality to render time We fixed an important bug in the way it handled colours, and implemented a new method of evaluating contrast. Two changes were made to the the robust adaptive sampler to produce better looking images in a shorter render time.

The robust adaptive sampler is ready for use in production.

More information is in the Path Tracing section below

The radio buttons for choosing between "Standard renderer" and "Path tracer" have moved to the Quality tab of the render node, and other controls have been rearranged to accommodate them.

"Defer all shading" is enabled by default.

"Robust adaptive sampler" is enabled by default.
