corona-10-3dsmax-daily-2022-11-25.exe

New

• Corona now correctly resolves in which volume the camera lies. The camera can also be given a non-zero physical size, in which case the camera might lie only partially in one volume (e.g. camera half-submerged in water)
• Clouds lighting now depends on the sun color intensity and direct input color settings (if selected in the sun properties)
• Decal Fit to Bitmap's aspect ratio function now takes into account also cropping present in bitmap (both Corona’s and 3dsMax’s bitmap)
• Added warning to LightMixSetup dialog, when some Light select element contains invalid filename character + replace those characters with '_'
• Added option to automatically create lightmix elements by 3dsmax layers
• Added tonemap control viewport shader (as no-op)
• Added ColorCorrectMap display in high quality viewport
• Added button to batch load maps in the multiple environments dialog. It works similarly to the one in Multimap
• User can now set how volume (volume material, sky volume effect and volume grid) interact with alpha channel. + Semi-transparent volumetric effects now also contribute to alpha channel for rays not hitting anything
• Added include / exclude toggle in the right mouse button menu for exclude lists
• Added tooltips for "+, Reset, Preset" buttons in Tone mapping
• CIE - Added tone mapping error reporting when loading an image

Optimisations

• Improved performance when rendering with masks
• In cases where the user includes just a small object and the rest of the scene is not rendered we get up to 600% speedup. In non extreme cases it leads to around a 10% speedup
• Improved caustics for higher resolution renders
• https://corona-renderer.com/comparer/u8CBuE

ChaosScans

• "V-Ray" mentions removed from the material information
• Material is transparent unless some file is loaded, to be consistent with V-Ray
• Added custom bump and displacement slots to CoronaScannedMtl
• Fixed incorrect albedo (displayed as red in albedo render element)
• User can now drag drop vrscans file into the dialog and it will load it
• Added drag&dropping an image accompanying the vrscan file open the vrscan file
• Added support for triplanar mapping in CoronaScannedMtl
• Removed legacy mtsc format from the file explorer filter
• We now show the preview of the material in 3ds Max viewport

Changes

• Re-Enabled out of core textures by default
• CoronaGUI license is released when another renderer is selected
• AO map: improved wording for include/exclude options

Fixes

• Fixed an issue with low CPU usage with CoronaAO and CoronaRoundEdges in IR
• Fixed rare crash occurring when IR is restarted during parsing
• Improved conversion of VRayMtl SSS to CoronaPhysicalMtl
• Fixed: Noise limit working incorrectly with black environment + fisheye camera in user scene, leads to infinite rendering
• Prevented crashes when there is nullptr Atmospheric when a plugin is missing (it will still crash in 3dsmax on opening atmospherics dialog though)
• Fixed issues with material editor previews being much slower to load than in Corona V7
• Fixed support of PhoenixFD in Corona 10 + removed PhoenixFD 3 support
• Fixed DR - Assets that can be found on node are not downloaded anymore
• CoronaMix map should no longer change the randomization when it is plugged into CoronaUvwRandomizer anymore
• Fixed: Viewport Performance is slow when Corona light IES has missing path
• Fixed: "Show in folder" RMB option sometimes opening incorrect folder
