How change ambient for material in code?
In editor you can change ambient color for material (Ambient Red, Green and Blue parameters). This is something I want modify in game, but when I tried use LinkShaderParamChanges and Renderer.ambient_color it dosn't work.

If texture technique is Default or Alpha Test nothing happans at all and with Blend Light and Test Blend Light it's overwrite all lighting for material.

It is intendent? If yes, how can change ambient color like in editor with LinkShaderParamChanges?

For that case you should set some initial Material.ambient value at the start (not zero) so ambient shader gets set up for Mesh. This requires additional drawing pass for that material.

Hi, I tried it, and it dosn't work at all. Objects in game have ambient that I set in editor, but it not change in game. I don't think my code is wrong, because I use it for material_color without any issue.

PHP Code:
changes.clear();
changes.New().set(Renderer.ambient_color).set(AmbientVec); // set its value
         
LinkShaderParamChanges(changes); 
mesh->draw(matrix);
UnlinkShaderParamChanges(changes);

Renderer.ambient_color is not for materials but for global ambient D.ambient.
