Is there a way to control the reflection factor of a skinmesh by a script runtime?
I mean the environment mapping.
For example, the reflection factor to be 0.5 if raining and to be 0.1 when sunny weather.
If somebody can answer, I will be VERRRY thankful!

this won't have anything to do with Environment Map reflections... (actually, it might)... but if you've set the object shader properties to 0015user_bumpy_glossy_tile, then you can use iShaderFloatSet() and iShaderFloat3Set() to modify the various properties that affect the appearance to make it gradually look more wet (cGlossy for example)...

also, a translucent (ghosted) copy of the skinmesh with scrolling uv could be used to simulate water flowing...

I know that but for roads it will be more effective if the reflection factor is adjusted. So if anyone knows how... feel free to share (shader, code, trick etc...) Thanks anyway, Mike for the feedback!

I like the screenshot. Looks very accurate.

Yes, of cource but I also use this effect. I want reflective roads, not boxes or other objects.

Also, controlling the reflection factor may be a graphical setting in the games. The glossy factor is really good idea, I've used it in one of my games, but it only reflects lightings.

Like here (a rainy road) - the reflection is not only from the light:

well if I want reflective roads I have to export the roads as different models and use the specmap bumper glossy shader.

then use the same technique on the road...

are you talking about your own custom roads or roads made from the highway construction pieces...

My custom, made from Skinmesh (the collision is hidden rigidbody). I don't use highway construction kits because they keep an unexpected collision lag.

I know that. I've been using the specmap shader, I've been using the glossy factor.

But the question was - is there a way to set the reflection (environment mapping) value runtime by a script or something?

i don't think that the environment map is what you're looking to change here... but to answer your question, i think the simple answer is no...

off the top of my head i don't have an immediate solution... except possibly using Genetransfer's Volume Cubemap shader...

there are going to be several things to consider trying to arrive at a suitable solution...

first... the road surface isn't reflecting the objects... its mostly the water that is reflecting things... in the real world i mean...

second... in 3DRAD, the object being reflected (skinmeshes) can be controlled via script as to whether they appear in the reflections or not... so that may point to a possible direction..

i think you've come up with the next real challenge PS... to see how close a 3DRAD scene can come to that picture...

How exactly?

Mike Hense · « **Reply #11 on:** June 03, 2014, 10:21:55 AM »

read the skinmesh help PS... all the way at the bottom it says...

INTERNAL PARAMETERS

The following internal parameters can be accessed run-time by using objects like EventOnValue or Script:
....
....
Internal flags (write-only). This parameter allows you to control additional functions for the SkinMesh object, as follows: set this parameter to 0 to disable 'Visible In Reflections' mode, set it to 1 to enable.

link all the skinmeshes you want to be reflected to a script and look for the internal flags property in the PUTPUT window... set that index to control the visibility in reflections...

THANKS VERY MUCH! I really did not read this at help, so I sorry. This is perfect solution of my purpose. Thanks Again!!!

it's easy to miss one line of info... there's a lot of stuff in the skinmesh help

Of course! Sometimes I lose the most important there
