Get access to 200+ hours of TouchDesigner video training, a private Facebook group where Elburz and Matthew Ragan answer all your questions, and twice-monthly group coaching/mastermind calls here: bit.ly/2zJ0lmt
If you’re a TouchDesigner Beginner, check out our TouchDesigner Tutorial Series! We teach you all the basics of how to use TouchDesigner, including mouse controls, hotkeys, parameters, the operator families, and more: interactiveimmersive.io/touch...
Elburz shows you not only a high level overview of how UVs work, but also dives into creating UV maps directly in TouchDesigner for geometry you have in your network. Once you have a UV, we create some simple content using the UV maps and how they can get reapplied to the geometry naturally so that your content is ready to be projection mapped with tools like CamSchnappr.

Really helpfull, with a light projecting texture(spherical render) and this tehnique you can do seamles stiching for full room video mapping.

Great tip! Glad to hear you found it helpful 😀

I've found when working with borders from the rectangle TOP, one needs to turn off anti alias on the rectangle otherwise that outside edge of the border has a bit of alpha in it at 1:1 aspect

That's a good trick, especially when you're working with rendering things that aren't "content", turning off anti aliasing is generally a good idea.

i guess it is kinda randomly asking but do anybody know of a good place to watch new movies online ?

unfortunately, my primitive sop never works out the different colors even I typed in exactly same lines... it seems this way only works for boxes, when it gets to the custom models it just simply won't work... thanks any way!

Oh no! What kind of geometry are you passing to it? Maybe it doesn't have more than one primitive (like if it's a single mesh). A good way to check is to middle click on the SOP before the Primitive SOP and see how many primitives it's reporting.

Super cool and useful. I tried this with a sphere but it seems to be more complicated. Anyone manage to find an elegant solution for seamless sphere textures?

@TheInteractiveImmersiveHQ 10 ай бұрын

Mapping to a sphere is definitely tricky! It's likely going to require a more involved projection mapping technique, like the one covered by Richard Burns here: kzfaq.info/get/bejne/iNOem7hnp664iI0.html. Also worth looking at these forum posts about UVs and seams for spheres: forum.derivative.ca/t/3d-sphere-how-do-i-fix-this-seam-on-my-texture/221408/2, forum.derivative.ca/t/triplanar-texture-mapping/180141/3. Hope that helps!

Hey! Is there a way to do it with multiple box combined with a merge? Even with a texture sop I can't find the right uv unwrap :/

@TheInteractiveImmersiveHQ Жыл бұрын

Hey! Definitely - it actually uses a similar technique but has a few more steps. Take a look at this post from the TouchDesigner forum where Markus Heckmann explains the approach : forum.derivative.ca/t/sops-how-to-unroll-a-curved-plane-into-a-flat-rectangle/318323/2. There’s also a TOX file included with the post which is helpful for seeing the technique in action. Hope that helps!

@@TheInteractiveImmersiveHQ Thanks for your answer! I tried everything in the example but impossible to make it work for now.. every time I import an assemblage of cubes (4-5 cubes side by side, fbx, obj or made in TD), it only gives me the uv map of one single cube. I definitely must be doing something wrong but I don't get it 🥲

Mr. and if the texture is an HDRI?

@TheInteractiveImmersiveHQ Жыл бұрын

Hi, you can use the HDRI file in the same way as we do with the banana test image in the second half of the video. You can use a Movie File In TOP, TouchDesigner treats it just like a typical 2D texture.
