Does Constructor support CAULK texture?

#1 Do you mean "tiled" (seamless) textures?
This depends of the use of texture. If you tile the texture over large space, then - yes.
If it is a texture that just needs to be set on one part (non-repeated) - then it can be any texture.

The only requirement - the size (dimensions of texture) should be "power of two": 64x64, 128x128, 256x256, 512x512, etc. Combinations accepted: 16x64, 128x512 - but the x/x should be not more than 1/16, e.g. 512x32 (1/16) is okay, while 16x512 is not - 1/32.

#2 I was going to check the things you mentioned just now, thank you for your reply. ;)

The caulk texture is another question, while define the caulk texture on the faces of a brush, the engine would not render these faces in game, this is a function of Q3A engine.

I wonder if TGE/TSE support the caulk texture? If not, is there any way to avoid rendering the hidden faces?

Thank you.

#3 IIRC in Ctor theres a pink texture... apply that to the face you don't want to render.

#4 Ah... got it. Thank you. ;)

#5 Ha! you are talking about NULL texture - yeah, that's the thing you need as Joseph said - use pink texture (it's the one with the name "NULL") - it will not be rendered.

sorry, I'm not that good in English, didn't understand what "caulk" means from first time :)

#6 I knew 'caulk' from quake3 radiant editor, I didn't know this word before, eighter. ;P
