How to make transparent textures
Hello all :-)

Does anyone have a suggestion how you can make semi-transparent textures?

I can think of several scenarios:
- Partially transparent walls: here I want to apply a texture to a wall. Where the GIF or PNG image is transparent, the wall should be transparent as well.
- Partially transparent objects: let's say I create a cube with a texture applied to one face. Where the image is transparent the cube should be transparent as well.

These images help explain what I want to achieve.

I tried some variations, but sofar without success.
Hopefully someone has good suggestions.

Re: How to make transparent textures
A basic search would give you many answers to accomplish this.
Depending on your system you can use one of the suggested solutions here: https://www.makeuseof.com/how-to-make-background-transparent/

If you only have a single image you want to convert there are many online sites where you can do easily this for free.

I always use GIMP. Basicly you add and aphachannel to the image and set the transparency to a selected color. The link I gave also explains how to remove a background for an image using different graphics programs.

Remember to save in a format that supports transparency, for example PNG. (JPG doesn't support transparency.)

Bonjour.

J'ai aussi découvert par hasard une possibilité de Power Point (pour ceux qui l'utilisent) et c'est très pratique.

Regardez la vidéo suivante.

J'ai testé et ça marche très bien.

Adobe Express, une application en ligne gratuite, est aussi très intéressante et très simple à utiliser.

L'arrière plan, qui apparait en blanc sur l'image, est en fait transparent.
