OK. Just found out:

Prepare a WAD with an animated texture from a set of texture bmps like +0vulcan.bmp to +9vulcan.bmp. You can add a set of 10 textures to a WAD in one go.

Create a block or prefab in an new empty level in WAD and add an animated texture to the block. Then compile this map with disabled "create meshes" (checkbox set off) as a >simple map< ! Save it out and import it into your WED Level, created with "create meshes" set before, by"ADD MAP". This way the very useful t7 functions and block animted textures do work together.

NOTE (!): Here I mean WAD animated textures from a set of bmps like +0Vulcan.bmp to +9vulcan.bmp only ! I don't know how to get animations
like *ooze going. I assume they need a special FX. Did not check this out.

If you need sets of animated textures you can use PCXanim, also available on this forum. Import a ten frame animation and export them with "export bmps". Enter a base name. Enumeration und .bmp extenter will be added automatically. Works ony with 10 frame animation.
Most PCXanim animations are good for simple scifi games. If you want ro create a world with next gen graphics you should get a professional version of GSTUDIO, which uses shaders.

The command "Tex_CYCLES = 10" let you set the speed of the texture animation.

Best wishes !
