Tips for speeding up 3ds Max

A helpful note from Aurtodesk Area blog.

Experiment with settings in the following areas:

If you use the mental ray renderer:
- Ray-Trace Acceleration, adjust the parameters for the BSP method,
- There is no way to tell a renderer to use more memory, however you can make sure that it's not doing its best to conserve memory by verifying that Conserve Memory in Rendering > Render Setup > Processing tab is not checked,
- see Zap’s blog post on mental ray thread priority to maximize render performance at the cost of interactivity (or maximize interactivity at the cost of a little bit of render performance).

Optimize scene where possible, use ProOptimizer on as many dense objects as possible. ProOptimizer Modifier Documentation
Right click on a modifier and choose Collapse All in the stack. This removes all history, so be sure to save the scene under a new name to avoid overwriting original scene!
Where possible reduce number of lights in scene:Fewer lights means fewer calculations and therefore faster render times.Use the Light Lister to disable lights where possible.

Disable Receive / Cast Shadows on objects not needing them:
- right click on the object > Object Properties > Rendering Control >Receive Shadows/Cast Shadows
Do the same for “Visible To Reflections/Refractions"
Disable/Exclude objects from Caustic and GI Calculations:
- right click on the object > Object Properties > Mental Ray, uncheck where necessary options for Final Gather, Caustics and GI, etc.
Reduce the number of reflections/refractions in the scene. Fewer reflection/refractions results in shorter render times.
Sometimes BIOS power-saving options can impact performance in 3ds Max:an example is the cstates option in the BIOS of Dell machines which can impact the viewport performance of 3ds Max. Switch off the power-saving options in the BIOS and instead use the ones in Windows Control Panel, that way you can adjust the settings without rebooting the machine.

Blender 5.3 brings native Gaussian splatting: what archviz artists need to know

Blender 5.3 adds built-in support for importing and rendering 3D Gaussian splats, eliminating external add-ons and opening photogrammetry capture as a native workflow. The feature works across Cycles, EEVEE and Workbench, but carries current limitations around export, transforms and color space handling.

Client Clarity Is Not Approval: What AI Visualization Actually Changes in Your Workflow

AI visualization tools accelerate early design exploration but introduce new risks in multi-view consistency, architectural accuracy, and revision control. Studios must anchor all work in a production 3D scene and implement structured approval gates before generation.
