ReVoltBlenderAddon

A Blender addon I created because I wanted to work with Blender 2.9+, and the existing one wasn't compatible.

What's Supported

World (*.w) export and import
Mesh (*.w/*.prm) export and import
Collision (*.ncp) export and import
Hull (*.hul) export and import*
Mirror Planes (*.rim) export and import

PSX Hull (*.hul) import*
PSX Mesh (*.psm) import
PSX World (*.psw) import

*this re-creates the hull based on it's vertices

Installation (Windows)

Place the io_scene_revolt folder in the %appdata%\Blender Foundation\Blender\2.90\scripts\addons directory

README: WORKING WITH PRM/M/W

The way you do flags etc has changed. The way I've written this is more of a WYSIWYG (what you see is what you get) approach.

• Texture number is based on the texture assigned to a material. Ex. if you assign "mytrack_a", it will export faces with this material as texture 0.
• Translucent flag is set by the "Blend Mode" on a material being either "Alpha Hashed" or "Alpha Blend"
  • Alpha value for vertex color is set by the "Alpha" slider in a "Principled BSDF" material
• Env flag is set by the specularity of a "Principled BSDF" material.
  • On tracks, hook up a Color node to the Specular input, this will be used as env color
  • On cars, just set the slider above 0 for env, or to 0 for no env
• Double sided flag is set by a material having the "Backface Culling" option turned OFF
• Texture animations are currently not supported
• Mirror flag is set by the "Screen Space Refraction" checkbox in material properties
• To setup an additive material, set it up as described on this page: https://b3d.interplanety.org/en/blender-eevee-transparency-blend-modes-multiply-and-additive/
• To use vertex alpha, add a "Vertex Color" node to the material, and connect the alpha output to the alpha input of the principled setup

The W exporter also functions as an alternative to WorldCut! Just select the "Split Meshes" option upon exporting.

README: WORKING WITH NCP

The way collision is setup has changed.

• Select your collision object, open the search menu, and locate "Setup NCP Object"
  • This will add NCP materials to the objects material list
• Camera only / Object only flags are done with Face Maps, these are in the "Mesh Data" tab of the object

README: WORKING WITH HUL

• Selected objects will be exported as convex hulls
• Any object named "HullSphere" is exported as a sphere
  • The size of exported spheres is the average scale of the object. To make a 'compatible' sphere model, create a 1 diameter UV sphere.

README: WORKING WITH RIM

• Any object named "MirrorPlane" is exported as mirror planes
  • Using "Selected Only" will override this behavior

KNOWN ISSUES

• PSX import may have incorrectly created materials
• PSX stores double sided polygons as individual polygons, and Blender doesn't like 2 polygons sharing vertices. So these don't import currently.
