Maxwell 5.0 - Release Notes

Maxwell Render

New Features

  • Nested references.
  • New procedural texture: Random Color.
  • New procedural texture: Random Uvs.
  • Emitter groups for multilight.

Changes

  • Searching paths include 3 levels of subfolders.
  • Multilight intensity override decimal precision at Mxi Batch Processing tool.

Improvements

  • Normals channel now shows normal and bump mapping.
  • UI for hi-dpi screens (4k and on).

Known Issues

  • Wrong data issues with TIFF images and LZW compression in Linux platforms (including Maxwell Cloud nodes).

Fixes

  • Using emixer files at MXI Batch Processing tool makes other changes to be ignored.
  • Noise procedural texture doesn’t use the seed.
  • If a texture is blended with a procedural texture and tiling is used, procedural texture uses squared tiling.
  • Selecting a folder on UI sets the path without final slash.Dropping a file on a path UI sets the file path wrong.
  • Crash when closing app if any field has focus.
  • Bad illumination patterns with high values of blur in spotlights.
  • Random crash using denoiser.
  • Switching between GPU and CPU engines at render time can make some emitters to stop working.
  • Slow render using custom alpha channel on 2 socket machines.

Maxwell GPU

New Features

  • Additive materials.
  • Multi-GPU rendering.
  • High resolution renders supported.

Improvements

  • Graphics Card driver version detection.

Known Issues

  • Crash when consecutive renders with different resolutions are done with multi-gpu.
  • Dielectrics materials don’t behave as intended on some scenes.
  • Some channels (alpha, material, object, position, z-buffer) may show artifacts.

Fixes

  • If an instance of an object has a material but the original object uses the default one, both of them use the default material.
  • Deleting BSDFs with FIRE-GPU “on”, makes other objects to change their material.
  • Object opacity clipmaps fails on some scenarios.
  • Ghost BSDF in combination with other BSDFs doesn’t behave as expected.
  • Some scenes have noisy caustics where draft CPU engine doesn’t.
  • Some monochrome images (i.e. TIF format) do not work properly in monochromatic maps (i.e. opacity).
  • “No tiling” feature on textures does not work.
  • Render Booleans are not interacting properly with indirect lighting rays.
  • Black emitter + BSDF makes FIRE to crash at stop.
  • FIRE-GPU can crash at material change.
  • Monochrome textures not being sampled properly.
  • Textures for opacity layers not working in emitters.
  • Re-enable a disabled material layer with FIRE running may crash.
  • Moving an emitter with FIRE running may crash.
  • Materials with roughness between 90 and 100 may not behave as intended.
  • Repeated textures are repeated on GPU memory too.
  • CPU memory peak on GPU copy.
  • Moving instances on FIRE-GPU may crash.
  • Changing resolution between renders may make GPU render to crash.
  • Multistep motion blur may have triangles disappearing.

Maxwell Studio

New Features

  • Render via Maxwell Cloud.
  • Render animations (from the Export animation tool) via Maxwell Cloud/Network.
  • Auto-save.
  • Open/Import V-Ray scenes (.vrscene files).
  • Added Linked Camera button in Fire window to connect/disconnect the Fire view to the camera movement.
  • Double click on a material on Resources Browser imports it to the scene.
  • Active view (rendering view) indicator in the 3D viewport.

Changes

  • Searching paths include 3 levels of subfolders.
  • Render and Fire CPU/GPU dropdown menus were replaced with a one-click selector.
  • Fire buttons were moved to the interactive preview window.
  • Fire Options dropmenu was replaced with settings and save buttons (right-click menu is still there).

Improvements

  • UI for hi-dpi screens (4k and so).
  • SL indicator on FIRE.​
  • Improved fonts and look of the informative text in the viewports and Fire windows.

Fixes

  • Some scenes crash saving MXS after render FIRE at high quality.
  • MXM alternative folder option is disabled at loading.
  • If a number with more decimals than the field precision is entered, the value changes to 1.0.
  • New UV channel have index 255 by default.
  • Maxwell Scatter: Scatter modifier guides are now pointing in the right direction (previously they were leaning towards Y=0).
  • FIRE crashes changing quality.
  • Moving instances on FIRE makes multiple objects on the way.
  • Changing camera aspect ratio with FIRE-GPU “on”, corrupts image.
  • FIRE forces re-voxelization on object transform edit.

Network

New Features

  • Maxwell Cloud.

Fixes

  • Network always render with production engine.
  • If denoiser is activated on scene, network denoiser options doesn’t override it.

SDK

New Features

  • MXS and MXI files have metadata.

Fixes

  • Crash editing MXI files with Simulens “on”.
