When I look at my model in viewer by doing; pip install panda3d-gltf, and running gltf-viewer $nameOfModel
or when I view my model online at; https://gltf-viewer.donmccurdy.com/
I can see my texture on the model. when I used to use .egg it showed the textures
My question I guess is, do we need to do something different to display textures
on our gltf models or is it just being glitchy?
I am just loading it in and reparent to render, (I do see it but no texture applied).
P.S I have been working super hard on www.shenko.org, panda3d and blender is a big part of my project. The last peice of my puzzle in testing is making the new gltf texture. any suggestions are apreciated.
gltf-viewer is making use of simplepbr to handle the PBR materials and textures coming out of Blender’s glTF exporter. However, I am surprised that you’re not seeing any texture as opposed to the color being off. Are you using Panda’s auto shader? Maybe give simplepbr a shot to see if that helps us narrow down the problem?
I’m looking into it now, my pip install threw up a error. I’m going to try the other manual install method. Just thought you should be aware.
$ pip install panda3d-simplepbr

Of course, this is not the best place to talk about it, but when I was editing examples for the GUI, I started thinking about Python versions and code that would work for everyone. I came to the conclusion that we need to use .format () for strings. But I would like to say this: we need to develop programming rules for Addons and for the code in the documentation. This should combine the community’s work into a single programming standard for Panda3D.
@serega-kkz, just getting into this whole programming thing and I completely agree with you, it is so frustrating sometimes. I had the same idea to make a ‘standard’ and post it on my website www.shenko.org, but just getting the thing to work locally is a problem. We’ll get there eventually.
@Moguri, My stock code black background, the viewer shows textured block/asset, but when I added your code (import simplepbr and simplepbr.init()) I do see a change but no texture (NOTE; I didn’t add the line super.init() I don’t know if that is why?)
You’re not calling the ShowBase constructor? If not, yes, you should be calling either super().__init__() or ShowBase.__init__() from your ShowBase subclass. ShowBase does a lot of its magic in its constructor (the __init__() function).
yup just checked ShowBase.init() is called at the beginning of my class, I swapped it out for super.init it runs with no errors but still no joy with the whole texture situation. Maybe its blender and the way I applied the texture? (we do see it in the viewer but i dunno).
I could leave it in wireframe for now, as I build up the rest of the project, come back to texturing later on.
The gltf-viewer really doesn’t do much special, and you can see it’s code here.
Oh, a thought just occurred to me! Perhaps Assimp is being picked to load the glTF file instead of panda3d-gltf? Could you try adding the following line in your ShowBase subclass prior to loading the model: gltf.patch_loader(self.loader)
It’s hard to tell what is the problem without the code or the actual model, but a common error is that you are not creating any lights in your scene.
gltf-viewer is creating a default light (or apply the lights from the model if any) that would explain why you see it correctly in the viewer and not in your app.
