    Hi. Is there a way to achieve emissive decals? If it's not already there somewhere in the shader, is there a plan to support it?

    Hi, this is currently not supported but is on our Roadmap.

    Note that the decal emissive will only add emissive on a material, not replace the emissive of this material for what we plan.

    Oh okay. Thanks! Is it not possible to provide an option to replace the emissive or add over the current emissive?

    Hi,

    Replacement mean it require to use an additional render target (in addition to the already additional target if you use metal and AO) which is not affordable for most games. So we will not provide the option. You are free to customize the code for your need as we can't cover each specific project need :)
