Day08: Tutorials Part 02 (Point Instancing & LSR)

This morning Ari mentioned that we might get to meet our industry mentor.
Someone from the industry that way pop by weekly and guide us towards the end of our shots.

Went through a video tutorial regarding instancing.
some screen-shots.

Instancing is an efficient way to save memory.
During render time, geometry will then be instance on the points.

 

With the point sop, added color with the expression $BBY.

If the expression is typed in the other color channel it will color it differently.

Scatter points

Scatter points base on the red color

Adding custom parameter into the point sop

Here are some renders.

Random scales

Random Rotations

Quick tip
Appending a box sop to a file-in geometry will create a bound of that geometry, that bound could then be use as a visualizing proxy geometry. Locking the box sop afterwards enables the file sop to be disconnected.

Also had Ari explained about point attributes in Houdini.
The points in Houdini is very different from other packages. Points have attributes like PScale, Colors and Alpha etc...
Knowing that when we copy geometry to points, we could have the point's attribute to be the geometry's template, so the geometry will scale if whatever size the point attribute have.

Next up UV, Lighting, Shading and Rendering.

Couple of my test renders.
Going for sunset look.
