Quote - How do you scale in the x,y,z co-ordinates of the nodes if it isnt in the node (ie the wood node)??
and secondly if i want to rotate the node how do i do that????

Thankyou to anyone who answers this...

Nodes that have a single "Scale" parameter, such as the Wood node, cannot be adjusted to produce unequal scale independently for X, Y, and Z.

Only the nodes that have Scale_X, etc. can be adjust to stretch the pattern.

Simulating wood textures is a really interesting topic. I have a lot to tell you about this. But we should not do so in this thread.

And, also, I'm sure you want to experiment yourself, so unless you tell me otherwise, I will not come right out and tell you how to do it well. However, I'll give you lots of hints if you like. Or, if you want to see how I do things, I'll show you where to look.

There are 5 key aspects to think about for the wood. Ignore any and you will fail to achieve wood nirvana.

  1. What coordinate system should be used to drive the wood grain pattern? Model XYZ? Global XYZ? UV? Related question - when you scale or stretch a prop, what should happen to the wood grain?
  2. What is the actual grain pattern? How do you ensure that you capture the nature of the different kinds of wood in a generic way? Look closely at oak, cherry, maple to start. How are they different or the same?
  3. How do you correlate bump with the grain?
    4) For stained or painted wood, how do you take that into account?
    5) For finished wood, how do you handle the finish? Satin, semi-gloss, and gloss all behave differently.

Finally, let me give you this clue:

The Poser Wood node is useless for wood.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
