Hello Lightwave 3D Luminaries,

I'm learning Lightwave 3D 2018.

...and...quality tutorials relevant to what you want to learn are a little hard to find. eg. I want to build 3d scenes e.g., Doors, alley ways, a street. I want to be able to model geometry from textures then paste the textures onto geometry. Kemal Gunel has created two tutorials relevant to what I wish to do.

The first one is 'press button', 'do this', press button etc. As such, it was a breeze to get the geometry ready for the textures.

The second one, below...is more of an overview. So it's a mystery to how to export the UV map into e.g. Photoshop (unless he did a print screen?) although I'm using Affinity Photo on the Mac along with Lightwave 3D 2018 on the Mac.

Questions.

1. How to create the UV map and export it (so I can cut up the texture in Affinity Photo and place them on the UV Map areas...)

2. How to bring that UV Map back in to Lightwave AND apply it to the model I have.

3. Kemal is using Nivida 'normal map' creating tools from their website. PC Only? How do I create a 'Normal' from the UV texture map and THEN load it and apply it to the scene in addition to the UV texture map?

It was all going so well for the 1st video...which was detailed.

But the 2nd video was 'only' an overview. It started off with the UV map in Photoshop. So I didn't know how he 'got there' and it's not clear how he loaded it back into LW and applied it to the model.

Any help you can give me would be greatly appreciated! :)

Regards,

Kyle.

Export as an .EPS file.

There are many excellent tutorials on creating UV maps in Lightwave on YouTube. This tutorial here (https://www.youtube.com/watch?v=Lfv9946K2Y8) is a good basic introduction to some of the concepts of UV mapping in Lightwave.

For export, you can use encapsulated post script (EPS). So, when your UV is laid out the way you want it, go to Save > Export > Export EPS and choose "Texture UV" from the View dropdown in the dialogue box. Name the UV and select where you want to save it to. I believe you can import it to Affinity Photo. You will probably need to resize it to the dimensions you want to use for your texture.


2. How to bring that UV Map back in to Lightwave AND apply it to the model I have.

If you mean how do you bring the texture back in to Lightwave, after you finish creating the texture in Affinity, save it as a bitmap (JPG, PNG, etc). Then you will apply it as a surface using the UV map you created. The tutorial I linked you to will explain the general idea.


3. Kemal is using Nivida 'normal map' creating tools from their website. PC Only? How do I create a 'Normal' from the UV texture map and THEN load it and apply it to the scene in addition to the UV texture map?

So, you can use an online normal map generator (Normal Map Online (http://cpetry.github.io/NormalMap-Online/)) and you might try Crazy Bump (https://www.crazybump.com/) for your bump maps.

Go through the tutorial and keep exploring for new tutorials on YouTube.

Hope this helped.

RPScmidt, thank you for the thorough reply and answers to each of my questions. Much appreciated. The LW Community is sound.

I'm looking at the youtube you linked me. The Normal Map and Crazy Bump are very good resources to use. I shall try to apply them to the scene I am making.

Much appreciated.

Regards,

Kyle.

Not sure if this is of any use to you, but it might help when you go to actually place the UV textures on the geometry:

As well as:

Plus this one for modeling from a texture that already fits the model:
