Does anyone know how they achieved this effect with the windows have some sort of depth to them.
As i moving to the side of the window the dark images become less 3 dimensional so I assume they’re not 3d models.
Hello!
I’m the current artist on Slime Rancher so I can say with some authority that GroZZler is correct.
The effect is pulled off by using three images set to different parallax depth in the shader. The deeper the image the more the emissive value is increased as well. No geometry needed.
Thank you for your reply it was quite an interesting read =]
Hey there, Well this is as good as it gets coming from the man himself.
I appreciate you taking the time.
While I have you here if you can answer one more question for me.
I remember seeing a video of someone with a map editor and whenever they’d move specific models the textures would transition, how is this achieve?
No
No problem.

What you’re probably seeing is world space triplanar mapping. This is when the UV coordinates of the material are defined by their physical space in the world and projected using one of three directions.

This has its benefits in that the model requires no UV mapping and also that the textures will always be a uniform scale/placement no matter how you scale or rotate the mesh. We use this method on almost all our environment models in Slime Rancher as a way of speeding up production.
I do all my shader work in Shader Forge. As such, you can see the exact node tree I use on their wiki here:

Okay I’ve manage to replecate both tri
Okay I’ve manage to replicate both, only I’m using a window shader script I found whilst googling that only allows one “3DTexture”.
How would I add multiple layers as I’m not to savvy with shader coding.
I tried duplicating alot of the code but ran into an error I couldn’t seem to fix.
