Parallel projection rendering problem

[Gleb Sharov]

Hi! Long story short, i want clouds to slightly reflect in windows when rendering a facade in parallel projection without photoshop. I tried placing an image with clouds opposite to facade but it didn`t work because when you press front view this image obstructs facade. Hdri didn`t work too because as i suppose it doesn`t work in parallel projection.

You can use a cloud texture as diffuse of the glass and give it some opacity..

this method will bring too much work if you have many windows

Use reflection override in material maps - environment overrides.. Add a clody picture, set uv environment and screen.. Adjust the value..

Hello, Gleb,
I would suggest experimenting with the Glass material's Reflection IOR value - increase it until you achieve the desired result.

Kind regards,
Peter
