Subject: Ecosystem and variable density


Qasar ( ) posted Sat, 27 August 2005 at 3:33 AM · edited Fri, 27 December 2024 at 12:53 PM

Bonjour, I experience some troubles using bitmap as fonction for variable density in the ecosystem. In fact when I use a terrain that have been streched or manipulate, the fonction didn't match the size of the terrain (ie instead of having one logo, I have multiple logos..). So, is there a way to stretch the density map in order to match the size of the terrain? Thanks for help. Qasar

Qasar, this might be because of the projection you use to map your bitmap on the terrain. You should use "object standard" or "object parametric", so the mapping isn't dependent on the world coordinates, but on the object's own coordinates. Also check that the image map you use has a size of 1 in the material editor, both in X & Y directions. If this doesn't help, post a screenshot of your material editor, so we can see what's going on.

Hi, Bruno021 Thanks for the answer. BUt unfortunatly your solution doesn't work. I just give an example of what happened. The terrain has not been modified, the texture is 800x800, the overall scalling is at 0.343 But I didn't find where is the "object std" or "parametric" toolbox. I just post three pictures

Just a litlle new thing, If I just change the overall scalling from 0.3 to 0.1, the result is that. But if increase the scalling, at tthe end nothing is generate.

Dans ton post numero 5, essaie de modifier la projection en utilisant UV Coordinates. Aussi, essaie de modifier la taille de l'image, dans le meme screenshot, en cliquant sur la fonction texture map. Si ton overall scaling de ton ecosystem est sur 0.343, il faut peut etre augmenter la taille de ton image. C'est bizarre, je n'ai jamais eu ce probleme.

bruno021, I should like to learn also what the problem is. Could you please supply a translation? :)

The problem is he's trying to get his ecosystem to match the image map he's using, but he's getting the eco twice on the terrain, as shown on post #3 And I was saying he should try and modify the projection of his map by using the UV coordinate input, and/or by modifiyng the size of the image map. If the overall scaling of the ecosystem is set to 0.343, maybe the image map size should be bigger.

Qasar,
brun021 had it right the first time. The mapping control is on the top-right of the Material Editor window. Select 'Object-parametric' from the drop-down list instead of the currently selected 'World-standard'.

Thank you bruno021 for the translation.

Will stick to english, so everyone can help, sorry!

No problem. I'm just learning Vue 5i and don't want to miss anything. :)


Qasar ( ) posted Sat, 27 August 2005 at 12:57 PM

OK, thanks a lot Bruno021... We need to turn the mapping to "object parametric" instead of "world std". You could experience it, with the latter a lot of lines, with the former only one matching the texture. Good point to know Thanks also SittingBlue Trouble for the help...
