Ok, Here's the deal. I'm trying to do a basic landscape. One Terrain, Two Materials, Each with their own ecosystem, trying to create a rocky path through plants.

Step 1, Create the Path on a 2d image.

Step 2, Create a material. Make sure Mapping is Object Parametric for Material. Make into ecosystem. Add rock. Use 2d map to create Distribution filter.

Step 3, Save previous material, then create new material same way, using grass instead of rock, and inverted 2d map for distribution. Save Material

Step 4, Create a Mixed Material. Use 2d image to Mix the two Materials. Save Material

Step 5, Replace Basic Materials in Mixed Materials with Saved Ecosystem Materials. (the underlying material has been left the same for ease of trial) AAANNNDDDD Here's the problem. As you can see, the Underlying Materials Mix correctly, The rocks are on the path, and the plants on the side, however they are distributed with mini versions of the path instead of filling the whole thing. My Question.....WHY?????

Here's what happens when I remove the Density map from the ecosystems but leave it as the distribution map for the mix. Underlying materials are still correct, but the ecosystems are still small, however they do fill the entire path.

And here's the closest I got....I removed the distribution map, but left the variable density maps on. The Ecosystem is now 100 percent correct, but the underlying materials are now blended forming the redgreen olive color. So how the hell do I get both to be correct at the same time? Please help!!! note - I realized above the for the 2nd and 3rd steps I mistyped Density maps for Distribution maps. Hopefully you know what I meant anyway. :)

Maybe the mapping changed from object parametric to world mapping during the process of setting up. Or the mapping is not consistent for all the materials.

Here is my attempt. I use simple the texture as distribution map to combine the 2 eco mats. Mazak

This version is quite different from your use of the map. You use Density function; here is the distribution function used. Mazak

I saw that page silverblade and that's what helped me get started. The 2nd and 3rd steps above use that method. The problem I'm having is when i try to combine them using a distribution map. That's what I'm trying to figure out. Sharon - It's not really a tut as It's flawed. If we can figure out what the problem is, then I suppose it could be a tut. :) I just don't want people confused thinking it's correct. Mazak - How the hell did you do that. You have two separate ecosystems forming a path. Did you have distribution maps on the individual ecosystems? If not, then how come that didnt' work for me. Post 6 above is that exact thing, but you can see the results are not correct. What's the difference between what you did and what I did? Thanks for all the help!! Dragontales

Mazak...I set up two ecosystems just as you have above. Here's my result. Why am I getting this. You can see the path pattern, but it's smaller and tiled. Someone please help before Throw the computer out the window. Dragontales

OK! I got some answers:

  1. make sure ALL MATERIALS are Object mapping Parametric! ie both of the materials before, combining, as well as final result MUST be paramteric.
  1. for testing this kind of thing use very clear basic matereals, not ecosystems, easier to see, use the checkerboard pattern material.
  1. Note that the SCALE OF DISTRIBUTION FUNCTION (in mixed material editor) and INFLUENCE OF ENVIRONEMENT may play a hand in final effects.

and here's finale' As said good tip is using basic materials ot check first: I saved as .vob objects just simple coloured balls. Using them for an ecosystem you can easily check rough work 1st ;)

Nope...still not working. Like I said above, the underlying materials work great. I get the path perfect, but the damn ecosystem objects don't work. They show up as the small tiled look. Perhaps you could upload the finished material for me to download and I'll see if using that helps. If I continue to have problems, then I know I'm having a glitch issue.

try this :) sorry named it density stead of distribution but it is for distribution filter :> Note object standard seems to work better for mapping in the individual mats that make the whole up but the final material HAS to be parametric mapped

Silverblade already said parametric mapping is important, make sure you have in distribution function image offset X1.00 and Y1.00 set. I hope it helps you. You can download my material too. Mazak

Thanks guys (gals?) I'll try them out tonight after I get home again from work. If mazak's material messes up too, then I know I have another issue. How I'll resolve that is a mystery, but I'll cross that bridge if it needs crossing. Again, thanks for the help. Dragontales

Dragontales ( ) posted Wed, 08 June 2005 at 10:56 PM

SUCCESS!!!!! But not as you would think. :) I downloaded the materials you gave me, and I STILL had the problem. I had vue check if it was up to date and it said it was. However I went to the e-on website and cross-checked my version number with their Beta Update. The Beta was higher so I installed it. After that your material worked perfectly. So...my advice to anyone trying to work with ecosystems....Install the Beta Update. :) Thanks for all your help, It really means a lot that others are so willing to help out. Dragontales
