Ortho lighting

When the scene is lighted with “Spot” or “Point” light sources, the rays from such lamps do not propagate in parallel. This makes noticeable distortion, for example when lighting with textures.

The parallel ray’s propagation (orthogonally to its plane) we can get from the “Sun” lamp, but such light source does not support lightning with textures.

Nodevember 2020

“Nodevember 2020” – the next challenge is coming from November 1 to 30  for amateurs and fans of procedural (node-) modeling and creation. The rules of the challenge are very simple – each participant creates one procedural material/object on a given topic each day with Blender exclusively using nodes. You can create whatever you want – models, meshes, materials, shaders, and even music, as long as they are procedural. Next, publish your created object on social networks with the #nodevember hashtag.


How to get the render pixels coordinates in compositing

When fine-tuning the finished render in “Compositing”, sometimes it is necessary to refer to the pixels coordinates of the processed image, for example, to apply effects distributed over the entire width or height of the image.

We can get the distribution factor of coordinates along with the height or width of the rendered image using texture nodes.
