Decals on transparent Materials - is there a loophole to achieve this?

[HannahHai1]

Hello guys!

Decals in Twinmotion cannot be placed on materials like glas which is a shame but that’s how it is for now.

I have however found a loophole where you use an opacity map on a solid material to create transparency. This way I can put a costum decal on the material. But as soon as I load in a png (with a transparent background) the whole graphic somehow has a blurred grey box around it.

I’m attaching some fotos here for you guys to see.

If anyone has a solution that would be sosoososo helpful.

Also is there a forum somewhere, where you can put in requests for Twinmotion if you don’t have a Pro Account? Cause using Decals on transparent Materials would be sweeeeeet.

I would genuinely be so grateful for any help!!!

Here with just the decal costum decal preface which seems to work just fine

Here with a transparent png which does not work at all even to I am using the mask.

And here without the opacity map for translusency with the same png & how it should look like.

I don’t know when or what changed, but it used to work. Maybe it was the 2021 version? It doesn’t work now. But you can get around this by creating a surface element and assigning it a material with an alpha channel. Then you place it on the glass pane. That’s all.

Hi.

Here’s something that annoys me about this software : decals don’t work on glass/mirrors.

I answered a question about this a while back.

Besides @Sturnus7’s solution,

Here’s a little alternative. Basically, whenever I have a decal to apply to a transparent surface or a mirror, I don’t bother trying 15,000 different versions anymore. I create it custom using Cinema 4D or another program (one polygon + one map + Uvs—> It takes 2 minutes) and apply it to the model.

Here’s a Jpeg to illustrate this.

Sincerely

K

Salut.

Voilà un « truc » qui m’énerve sur ce logiciel : les Décals qui ne fonctionnent pas sur du verre/miroir.

A l’époque j’avais répondu à une question de ce type.

En dehors de la solution de @Sturnus7

Voici une petite alternative. En gros, dès que j’ai un sticker à poser sur une surface transparente ou un miroir je ne me prend plus la tête à faire 15000 essais, je le fabrique sur mesure via C4d où autre (un polygone + 1 map + UV —> ça prend 2 minutes) et je l’applique sur le modèle.

Un petit jpeg pour illustrer ça.

Cordialement.
