HQ plants vs XFrog
« on: June 11, 2013, 01:10:11 PM »
Hi

As there are noe forum group for XFrog, I post this one here.

We have just purchased the complete library from XFrog and installed the XFrog Catalog.
The first thing I noticed is that all the models from XFrog are very dark.
I use 3ds max and VRay. I converted the materials using your script.

Is there any way to fix this within your script? One of the main different is the lack of glossines on the leafs on the XFrog models.

As the models are now, they are almost usless to us, unless we manually fix the materials for the models we are going to use.

Kind Regards
Ramboll

I just created a specific forum for XFrogPlans and moved your post here.

Regarding the problem, we have done some tests but the plants look right, both using standard materials or optimized with the script. Would it be that XFrog textures were loaded using a wrong gamma setting ?

Hi

Sorry for the late respond, it has been crazy much at work.
Can you please use the 6 first models from the XFrog Europe 1 package and the 6 first models from the HQplants 1 package and see if you get the same result?
I selected the models from the library and used your script to convert the materials to VRay.
The XFrog models also used A LOT longer time to render.
I have also attached a printscreen from my gamma settings.

Kind Regards

What Max version ? In Max 2014 gamma settings changed slightly, so i want to be sure to reproduce the test in same conditions.

Hi,

I've only been using the Xfrog trees since yesterday but I've noticed the same problem with the very dark trees. It doesn't seem to affect all of them though. Some render very dark some render fine... in either standard or optimized materials.

I'm using 3ds Max Design 2013 if it helps the discussion.

Yes, i can confirm some models look too dark, i.e. Austrian Pine from Europe 1. Since XFrog is a generic library (not specificaly designed for Max), i think the rendering result may change drastically depending of the platform.

I've tried several settings, and i got the best result using a multiplier at Bitmap->RGB Level (i.e. 5). If that helps, we would include such multiplier to the Material Optimizer. Obviously, we cannot know what textures would require one or other value, so is responsibility of the user to test different settings, ​​to get the best result. I'm afraid we cannot do much more in this case.

If you could imlement this option i the Material Optimizer it would be of great help!
The way it is now it would genereate to much work to do it manually.

Just done. I've added a "RGB Level" parameter to the Material Optimizer. It's applied to all diffuse maps, except those excluded by name ("trunk", "bark" and so).

The default value is 1.0, and setting 0.0 preserves the current level in the texture map. It's possible to "optimize" repeatedly to try different settings at render.

To install the update, copy the attached file to <maxdir>\scripts\forestpack.

Update: this modification is already included in Forest Pack 4.1.2

You can find here a thread discussing about HQ Plants vs XFrog: http://forum.itoosoft.com/index.php?topic=1746.0

Regarding animation, none of these libraries includes animated models, although there are tricks to fake the wind movement:

Alternatively, with Forest Pack you can use parametric models that include real wind, as GrowFX.

Having read everything I can find here I'm still having dark trees on Max 2016 with VRay 3.2. I had VRay 3.3 installed and thought it might be an issues because 3.3 is so new. But with 3.2 I have to crank the 'RGB Level' in 'Material Optimizer' up to nearly 10. I don't think this is what's intended and that I should be able to just  set the RGB to 2.0 or so to give it a little bump. Is RGB 10.0 indicating another problem or should I just ignore my gut feeling that this is pushing it too hard and set it to 10 and be happy.

Hi,

Well, we are not allowed to modify content of any third vegetation models and honestly we don't know which textures would require one or other value. In our tests some of their textures worked better with RGB Level set to 5, so might be even the vaulue of 10 would work fine for some. 

Anyway, as far as we know Xfrog has done material changes on its models and most of them should be "V-Ray 3 ready" now.

I would suggest you to get in contact directly Xfrog Inc by using this form.

Best regards,
