[Genhis][2.0.66] apply_runtime_tint breaks light_animation in additive blend mode

[TheKingJo]

TL;DR
runtime tint breaks when using additive blend mode in the light_animation of a car prototype
Long Version:
In the following image one can see the comparison between the same layer definition of a car prototype's light_animation, the only difference beeing the apply_runtime_tint. (For simplification it is the only active sprite)

The spritesheet contains 128 rotations which look similar to:

With colors being white with alpha gradients. The player color was the default orange yet the car underground light is black. I would've expected it to look orange.

When put into the animation property however, the result is as expected and shows up orange:

Thanks for the report. Can you share your mod for testing and explain why using animation is not a good workaround?

Uhh the mod is Lamborghini Aventador, but it is using a parent mod for entity setup and is also having a different sprite setup now, until this issue (if it is one) is fixed. But if you want I could quickly set up a proof of concept mod with the 4 version of working/not working graphics.

The reason I wanna use the light_animation is simply that I want the underground light of my car to only be active when it is dark ^^
Ofc otherwise I could just use animation

[TheKingJo]

I've made the test mod now. 4 cars in the unsorted crafting category

1. shows the not working tinted additive light_animation (black)
2. shows the working normal additive light_animation (white)
3. shows the working tinted additive animation (orange)
4. shows the working normal additive animation (white)

Thanks, it's fixed for 2.0.67. It wasn't related to additive blend mode specifically.

[TheKingJo]

Oh nice ^^

And sorry for not testing if it's even caused by the additive blend mode ^^
