How to replicate SketchUp texture re-color?

[Phantom107]

Hey everyone,

We’re having a problem with the development of a feature in our rendering platform for SketchUp.

When rendering, when we detect one of our own materials, the system is rigged to swap it out with a highly detailed PBR (Physically based rendering) version so it looks good.

We want to support people to use SketchUps color tool in the ‘Edit’ tab of a material, effectively allowing to re-coloring a material. To make this work for our own materials, we need to know how the color code works so we can try and replicate it. We can read out the RGB value but do not know how to apply this to the texture to get the same result.

Any help?

Best,

Guus

About colorized textures

How does colorised texture work?

Hi, I want to know how colorised texture works exactly. I read that the texture is first converted to gray scale and then the color is applied on top of it. I tried doing that, multiplying color value with gray scale texture color values. This doesn’t work. I also read that same hue from color is applied to the gray scale texture. Can anyone explain this? Do we need to add colors in HSL space?
