Community Beginner ,
Jan 31, 2024 Jan 31, 2024

Hello, basically im new to substance painter and i made my first texture ever today but when i export it to roblox it doesnt work (basic gray color)...The problem is, I think "User "MapExporter" The "Opacity" input map used by the "DefaultMaterial_ColorMap" map in the "DefaultMaterial" texture set is not available, because : The "Opacity" channel is missing from your texture set." But where do I find this opacity thing ?

 

Can u guys help me pls ??

The UVs will always be related to the mesh. You do not need to unwrap your mesh, because it is already done (with the automatic unwrapping feature). Therefore, as long as you're happy with your texturing, you can simply export the mesh from Painter and import it into UE5.

However, if for a reason or another you need different UVs, you can Reimort your mesh, as long as the proportions of the geometry stays consiste

Bonjour @Eliott35160909em7w ,

 

Comme votre Substance Painter est en français, je me permets (let me know if you want to switch back to english).

 

La map d'opacité n'est sûrement pas le problème dans ce cas précis. L'erreur indique que le préset d'export contient une texture qui n'est pas présent dans votre projet : L'opacité

L'opacité est une texture en valeurs de gris qui indique où l'objet doit être opaque et où il doit être transparent. C'est une texture qui n'est pas obligatoirement utilisée, puisque une majorité de projets n'en ont pas besoin. Etant donné les screenshots partagés ici, je dirais qu'elle n'est pas nécessaire, mais si je me trompe, vous pouvez ajouter la map dans Texture Sets Settings > Channels > + 

 

De mon point de vue, le problème provient des UVs. Avez-vous utilisé la fonction auto-unwrap à la création du projet ? Si oui, cela va donc automatiquement déplier les UVs (la carte qui définit les textures) et par conséquent, il faudra également exporter votre mesh (File > Export mesh) de Substance Painter, pour l'importer dans UE5.

Hello, thanks for answering me both in Discord and here (and yeah im french so you can translate/speak french if you want). But there is still a problem, I don't see the texture sets settints in my layers. I've watch this "tutorial" https://www.youtube.com/watch?v=IgvIGndKNCQ&ab_channel=MichaelTanzillo on this but didnt find out. Also I didn't unwrapped at all so maybe the problem come from here I'll try that.

Best regardes, Eliott.
