Auto-Blend Two Similar Images With Gimp: A Rendering Tip
Ok, this is a shitty rendering, but it serves it’s purpose here. I needed to blend two rendered images to make a composite render (more on why later).
So, I opened one image in Gimp (free, by the way if you don’t have it), the next I opened as a layer. Then, I went to Filters-> Combine -> Depth Merge. Select the two sources (the layers) from the menu and then slide the overlap bar to 2.0 and click “OK”. You’ve got yourself a blended image.
Why I needed this: Revit’s rendering engine is shitty. When there are interior lights and a sun source, the interior lights are barely visible. The answer: by rendering twice and blending them in Gimp, I keep the interior lights from the first image and add the residual light from the second.
Ok, after reading this I know you will appreciate this. It is free to download and use and is from Manchester University, which makes me proud as an alumni :D
