GEO STUDIO PRO 4.0.2 RELEASE NOTES

⦁ The application and Geo Format VERSION have increased to 4020 (4.0.2)

⦁ Previously the GLTF/GLB importer didn't handle GLTF Nodes that had children AND referenced a mesh - this resulted in the Node's mesh not being loaded. This has now been fixed.

⦁ We've made major improvements in the usability, tool compatibility, and stability when creating, editing and using Instance Node's in Geo STUDIO. These improvements were a natural extension after the overhaul of the Group Node's Transform List property. Here's a short recap, so everyone is aware of what Instance Node's actually are. An instance node references another Scene Graph node (which can represent anything from a billboard Tree to a complex 3D model.) The Instance node draws the referenced item with its own set of geometry transformations. This allows you to display multiple different representations of the referenced item without incurring memory overhead.

⦁ Added support for the GLTF material extension: KHR_materials_unlit. Its a switch in the PBR Material that disables all lighting calculations for geometry using that particular material. The PBR base color RGBA along with alpha mode and alpha cutoff are the only PBR properties available while Unlit is in effect. The result is flat shaded objects for when you need geometry to stand-out and not disappear due to shading effects.

⦁ Added support for the GLTF material extension: KHR_materials_specular. This extension adds two parameters to the metallic-roughness material: specularFactor and specularColorFactor. Specular allows users to configure the strength of the specular reflection in the dielectric BRDF. A value of zero disables the specular reflection, resulting in a pure diffuse material. The metal BRDF is not affected by the parameter. SpecularColor changes the F0 color of the specular reflection in the dielectric BRDF, allowing artists to use effects known from the specular-glossiness material (KHR_materials_pbrSpecularGlossiness) in the metallic-roughness material. In addition this extension provides 2 optional properties - SpecularTexture and SpecularColorTexture. SpecularTexture is a texture that defines the strength of the specular reflection, stored in the alpha (A) channel. This will be multiplied by specularFactor. SpecularColorTexture is a texture that defines the F0 color of the specular reflection, stored in the RGB channels and encoded in sRGB. This texture will be multiplied by specularColorFactor.

⦁ Added support for the GLTF material extension: KHR_materials_ior - the Index of Refraction. The dielectric BRDF of the metallic-roughness material in glTF uses a fixed value of 1.5 for the index of refraction. This is a good fit for many plastics and glass, but not for other materials like water or asphalt, sapphire or diamond. This extension allows users to set the index of refraction to a certain value.

⦁ If a Geo file had a Header Node with a Label defined - when you opened the file - the label was shown but the label text input widget in the Header attribute was blank. This has been fixed.

⦁ Fixed a number of bugs and inconsistencies associated with the display and operation of the Group type node's Transform List property.
