Preparing Materials for glTF
-
Hi Dr Sassi,
Thanks for the advice. I've watched the video through a few times to try and understand what's going on. If I'm understanding this correctly, the texture image doesn't fit on the plane as desired due to the squares being distorted. The points being moved in the left hand pane are being used as a reference to re-map the image to fit properly into the four square polygons of the plane. Am I understanding that correctly?
Kind Regards

This is correct, DaveMDarcy!
I love your precise way of learning and communicating.
The main idea here is that this drill creates the connection (between hand-eye and brain)βhence, it needs to be manually done. This provides the interaction needed to put the seed into place.
The target of UV and a proper setup is that we get an equal distribution over the whole project, even when the polygons vary in size.
On the other hand, you can also provide more pixels for the area of interest, while parts hardly in the render might need a little less. Of course, if that kind of optimization is needed.
I'm sure you will feel familiar very fast. Many great tutorials are available; let me know what you would like to learn next.
All the best

Hi Dr Sassi,
Thanks again for the advice, and the feedback I assume the next step then is to learn how to export a UV map so that I can paint a texture for my model and apply it, and then learn how to bake the procedural based shaders (that I've already made on my existing models) in order to use them in the same way as textures?
Kind Regards

Hi David,
Have you explored Paint, or as it was called, BodyPaint 3D?
It is like Photoshop, but painting on objects. Or do you already have an application that you are more familiar with, like Procreate (iPad), which allows you to paint on models as long as UV data is sound?
Please let me know.
Cheers

Hi Dr Sassi,
No I haven't got into Paint yet. I'm still only on the very basics of Cinema so I've not ventured very far from the basics I'm very familiar with Photoshop though, I've been using that for many years. I haven't heard of Procreate.
Kind Regards

Hi David,
Typically, the reply is, "I'm more familiar with Photoshop," and learning Paint in Cinema 4D feels a little bit uncomfortable the first hour, especially when one is very comfortable in Photoshop.
Adobe has less and less attention to 3D in Photoshop, hence my suggestion. (Procreate is not a Maxon App, but very popular on iPad.)Well it is late here (WestCoast) but I can't help it, here is a one minute screen capture for Paint. It is more profound, but just to give you an idea.

Check the material manager. Sometimes, a material has a red x, which means it is not loaded. To save RAM, click on the red x, and it loads.
Enjoy

Hi Dr Sassi,
Is that the West Coast USA? I'm in UK where it is morning now. I thank you very much for your time. The only reason I mentioned Photoshop is because I'm hoping it will help the leap to Paint not as difficult I've just found in Cineversity a three part tutorial series called 'UV Workflows', that look like a good course. Also thanks for the link to the video, I shall watch that now.
Kind Regards

Hi David, yes, California, and I called it a day after recording the clip for you, hence the delayed reply.
Yes, Photoshop knowledge is helpful, except for the muscle memory The interface and workflow are different, but the idea of Brushes and Layers, which I think is an essential part of Ps (user since 1993 here), is there. Well, there is one "Ps" layer package for any layer of the old material system.
The advantage is, that you work on the model directly and get better feedback. (Standard Render).
All the best

Ooh nice, I'd love to visit California, hopefully one day I will I did part one of the UV workflow series today with Mr Noseman. There was loads of great info there, I learnt loads. However it also revealed just how deep a subject UV's are! I will continue to practice your drill until I can remember it by heart
Kind Regards

Hi David,
You are in good hands with Noseman.
Please remember that UVs are one of the most avoided themes, but if you walk through this material, you will feel empowered. Fingers crossed, you will enjoy that feeling very soon!
Cheers
