Just a simple performance Question, but in my example, is is very important.
I have two Materials for my trees.
One for the leaves, one for the trunk.
Then I have lots of instances of each material.
In this case, i use my leaf material for the leaves and for the Billboard LOD at verry far distance.
And i just would like to have the possibility to disable wind in the Material Instance.
I got 3 options:
Use a “Multiply” Node. Wind multiplied by 0 results 0.
Use the “Lerp” Node and Lerp between the Wind an 0.
Us a “static Switch” with a “static Bool” Node and compare between the wind and 0. (I know, it creates a new material by switching, but does it also create one my multiplying by 0?)
And also: can I save some performance by disabling Wind this way?
What sould I use, from what can i get the most performance out of it?
Thanks!
If you use multimply out lerp sistem aniway calculate all nodes you got in wind. If you use a switch node our switch parameter and in false set value to 0 our 1 depend what you want to be default value, it dont process the calculation until the condition become true. So you can make a realy complicated master material with alot of switch, and make them like parameters and with a mater material enable our disable what you need in different material istances, and it use minimum ammout of calculation in function what you enable.
I got a realy complicated master material that can arrive to more that 1000 calculation but if I got all disable it making 80 calculation
to see the difference
set a switch parameter
make a istance of your material (right click on material Create istance)
Double click your istance
After it calculate default material you got up on left side on the preview how much istruction your pc need to calculate to make this material
