Hi Kent,
I completed the session tutorial with no issues and have now moved on to the session practice but have run into an issue. I've just used the same nodes for the planet textures here but the textures don't seem to be applying. When I plug the colour ramp directly into the viewer I can see them but cant see the textures when I plug it all into the Principle BSDF. Any idea what I'm doing wrong? Will attach pics in the reply
Thanks
Have you applied the scale for the planet? You can press Ctrl+A in object mode, and Apply Scale.
Also, since you are affecting only the roughness and the specular, you will notice the texture better when there is a bright light and you move around your view
Hi William eearthminer1 ,
Make sure to preview your Texture, before doing any Scale Applying! If you are happy with how it looks, you should not Apply the Scale, otherwise you'll have to change you Noise Texture Scale again. This is because you are using Object Coordinates. (More on this in Chapter 3.)
Martin cgtin is right about the lighting. You can also plug a version of the Color Ramp into the Base Color of the Principled BSDF. And while we're at it, I find it highly unlikely, that you want to use the same values (i.e. the same Color Ramp) for the Specular and Roughness.
It kinda looks like Eevee is still in the process of calculating the shader nodes before it displays the result. But I don't see a shader compilations progress bar..strange.
If the problem persists, I'll be happy to take a closer look. The best way to do this is by uploading your file to Dropbox, Google Drive, Mega, or equivalent file hosting service then copy + pasting the share link here.
Speaking of shader compilation progress bar, Blender rarely displays it for me. The bar that appears below when shaders are being compiled, yep that same one. I don't know why and I've always been like meh, ok Skynet, I'll see you in the battlefield.
