This looks way better than what I have seen the last time I checked out GPU rendering. Thank you for sharing. Impressive how fast this has developed in the last few years. Kind of wondering now how much time this took to render and how much they were edited after rendering.
If you skip to the 39:00 mark in the Blur video, you'll hear them discuss how they evaluated several Renderers and chose Redshift 3D. They mentioned going from hours per-frame on a CPU farm, to 5-20mins per-frame on a GPU box.

Thanks for all the input. I will try Houdini as soon as the download is complete.
In the meantime I am watching videos of snakes on youtube. Now I really want to figure out how I can create spline like ik chains…
Never considered using a gpu renderer for previz. Not sure how easy it is to use the same materials for different render engines.(unless I use an engine that supports both cpu and gpu) Will definetly give it a shot when I have nothing else to do/learn.
Dude, GPU Rendering is here and is thriving in Final Frame rendering, PreViz is an afterthought. Redshift is being used for Film, TV, VFX…you name it…by big Studios.

TheCrisis
Daryl Dunlap can you share this scene?
I dont have it anymore actually, but if you're still having issues with instancing, I can recreate it no problem.

Ok I have different problem with instance. How to transfer random, or custom attribute from point to instance. For example, color or scale or rotation. In attribute wrangler?
As of the time of this writing, Redshift does not automatically extract custom attribute data. There are some attributes that are automatically extracted, these are detailed in the FAQ section of the Redshift for Houdini documentation. For custom attributes, you have to manually identify them for scene extraction on a per-OBJ basis.
These steps and more are outlined in the RS for H Docs.

Couldnt do a Forum search to see if anyone has already talked about this…but…this sounds like a wonderful product to marry with Houdini. Especially since Indie can use it too (Thanks SESI for that btw).

I was looking for some information on Houdini Engine in Unity and I noticed that the forum search does not work.
At any rate, I believe I saw a post about an updated Instancing workflow in Houdini Engine…but I cant find the post now.

Gulp…is that some kinda Mantra erection I see? LOL
I think SideFX should do these every year, I'm finally getting a chance to use all the knowledge I've gained from all those Vimeo tutorials I've watched in '16.

Taking my time here….making everything procedural that I can.
It's actually a fun exercise.

Throwing my hat in the ring. I'll start by converting one of my old CAD models into Houdini.

Very nice start. I need to find a direction to go with my entry as well. Looking forward to your progress. I made need some sub-d tips along the way.
Happy Hunting.

edit: On second thought, scratch that, there's no way I'm going back to CPU rendering (Mantra) now that I've tasted Redshift 3D's GPU rendering power.

jeff
If you are doing the material assignments yourself, the way you assign materials could make things a lot easier. If you are creating scenes for others to use, you can use bundles or categories to create material assignments that would not only allow you to preview material assignments but to also edit them at a high level.
Jeff, can you elaborate a little more on how bundles/categories can be used in material assignment/management?
EDIT: Are you referring to Bundles and the Parameter Spreadsheet? I'm familiar with that workflow and like it.

Well, first off, this forum isnt monitored by Redshift support, so I'd post any RS related question to the RS forums at www.redshift3d.com
At any rate….
Lets say you have the following OBJ's: Box, Sphere, and Torus, these are our Source OBJ's
We then need another OBJ that will be our Instancer. This can be any OBJ really, but I prefer to use the Instance OBJ because it has native viewport support.
So, drop an Instance OBJ, and set it to Fast Point Instancing.
Now all you need to do is create some points on the Instance OBJ and add a string point attribute called “instance” and give it a per-point value that is a path to one of our Source OBJ's.
At this point, you will get the same result whether you render using Mantra or Redshift.

What problems are you having? Redshift reads the “instance” point attribute to provide instancing.

It works as excepted even If I assume it should better way to do this.
There is a better way.
A Point Wrangle is executed in parallel automagically….you dont have to manually loop over the Context elements.
So…you can replace you're entire vex code that has the for loop with a single line:
@P = set( (@ptnum/10)%10, (@ptnum/100)%10, @ptnum%10);
A Wrangle has a Context (Point, Vertex, Primitive, or Detail). The Wrangle context determines how many times the Vex code is evaluated.
A Detail Wrangle is only evaluated (1) time, since Detail context is singular. A Primitive Wrangle is evaluated for (n) number of Primitives on the object, same with the Vertex and Point context…it depends on how many there are.
So, in your example, you have 1000 Points, and you've created a Point Wrangle. So, the Vex code you write inside the Point Wrangle is evaluated per-point, which in your case, this is what is happening with your current code that has the for loop:
Vex code is evaluated for Point #1
@ptnum value is 1
Vex code sets the value of @P for Point #1 1000 times inside a For Loop
Vex code is evaluated for Point #2
@ptnum value is 2
Vex code sets the value of @P for Point #2 1000 times inside a For Loop
What this code
@P = set( (@ptnum/10)%10, (@ptnum/100)%10, @ptnum%10);
Vex code is evaluated for Point #1
@ptnum value is 1
Vex code sets the value of @P for Point #1
Vex code is evaluated for Point #2
@ptnum value is 2
Vex code sets the value of @P for Point #2
Hope that makes sense.

So, I assume you are measuring the angle between 2 vectors to determine which set the resultant angle belongs too?
…which would mean you are modifying one of the vectors (via vex rotate) and are expecting the resultant angle to be a specific value, and instead, you are getting some variance?
Is that an accurate problem statement for your scenario?

VEX trig functions expect radians not degrees.
You can wrap your values in a call to radians() to convert from degrees to radians.
