Hi all!
This might be a strange question, but what would be the normal texture
size today when creating content for games?
I'm trying to learn a new profession and need to test out the basics
at home before I jump out into the void :)
Also, would unity be a good practice platform? Or any other
well, let's answer the questions first:
1) Does anybody have source code they are willing to share for custom ICE Nodes
that deal with topology and/or geometry?
2) Does the lack of reference, location, and execute ports for custom ICE nodes
mean I cannot cast a location search from inside an
I haven't had much to do with games for the last two years so some info

both in terms of features and affordability.
As for textures, it totally depends on what type of asset you want to
build, and for which Platform
Hi
As a game artist it's very hard to really answer :D
I used to make my textures usually in 2k*2k and downsize for the needs.
Usually I meet always requests, like the texture is good, could you make
it in bigger res? So a 2k is a safe size, you can deliver any size
fitting to the rule of power
Hi Stefan,
I don't think there is a normal size.
It will depend on your platform specs and type of game. If it's a fighting
game, you may use more resources because it will display less characters at
the same time than a strategy game.
In a fight game for PS3, we used 1024 for the body and 512
And if we are technical details, number of vertex data matter a lot
(depending on engine of course) So the number of UV islands, hard edges,
materials are affecting performance too. And the texture compression
too. I was working on several games when I was working as a freelancer,
and there were
Well, you can look at it from two different points of view:

content with heavy iteration.
b) Do what many game programmers do and try to be efficient.

Very good writing Matt, I love the part you wrote about the 5000-1000-400-5000

well), and lead artist was sensitive to the UV

We use SI for 1unit = 1 m. That's our habit :D But it depends on the

I once tried to cast rays from a camera to points in a pointcloud to determine visibility.

From my small experience about this, you can't make a custom topology or
kinematics node, you make a node that abstract the more or less complex
computation, then you feed the topology nodes (or a matrix in the case of
kinematics).
As you stated you can't use locators, or location queries in a

If you are using while and repeat nodes to reparametrize the surface, you
are paying a ton of unnecessary costs. Yes, those things are slow, no, they
are often not required, which is why both me and Ciaran had the same hunch.
Matter of fact, I very recently worked on an equivalent problem, but
For topology, there is no SDK access. But a custom node can do all the low
level stuff (manipulating the so called PolygonalDescription).
Same for Kinematics, a custom node can manipulate a 4X4 matrix.
At the end you need to set the topo/kine using the corresponding attribute.
Here is an example

Oh yes the graph validation becomes a huge pain after a certain number of nodes. I had projects where it took 30 seconds just to

I didn't know it was called the graph validation but this problem happens
to me as soon as the scene grows over a certain number of point

That should work.

It means that you can't get the Topology attribute inside your custom node to
