In PixiJS runtime, how can I adjust some of the parameters in the Unity runtime

NijiNeko

How do I adjust Material -> Straight Alpha Texture, Texture -> sRGB (Color Texture) and Texture -> Alpha Is Transparency parameters in Unity runtime in PixiJS runtime?

NijiNeko Sorry for the late reply. The spine-pixi runtime does not provide a parameter to manually set whether a texture is PMA or not, but I think it would be better if you could tell us exactly what you are having trouble with. In spine-pixi, PMA textures are used even in the examples, and I think you should use PMA textures unless there is a very special reason not to. Is there a specific reason why you need to use straight alpha textures? And have you encountered any problems when actually using it?

In PixiJS runtime, you can adjust texture filtering and alpha settings by modifying the .atlas file and the texture settings in your code. For smooth edges and anti-aliasing, ensure that the filter entry in your .atlas file is set to Linear, Linear instead of Nearest, Nearest. This can be done by exporting your assets with Linear as the value for Filter min and Filter mag in the Texture Packer Settings. Additionally, you can manually update these values in your code if needed. PixiJS does not have direct equivalents for Unity's sRGB (Color Texture) and Alpha Is Transparency, but you can manage transparency and color space through shader adjustments and texture settings in your PixiJS application.

Spinebot Sorry, I don't quite understand, this doesn't seem to be what I need

Misaki Because the animator used a lot of Bleed instead of Premultiply alpha when exporting, if these three options are not enabled, the light will be overexposed after rendering. Hundreds of assets have been used, so there is no way to modify the assets themselves.

NijiNeko If the original Spine projects have not been lost, a few hundred projects is not that many. Using the export shell script that we made available, you can re-export all Spine projects within a specific folder. Unless re-exporting is truly difficult, I recommend repacking the textures in PMA.

Davide, who is responsible for the spine-pixi runtime, will be away for a while, so he may be able to advise you when he returns, but for now, I think it would be best to look for an easier way to repack the textures.

Misaki At present, we really can't repackage everything, so we can only hope that this problem can be solved.
