Need help with objects.

I need some help with the objects I'm porting to Terragen 2. I can get the glass in the object transparent but am having difficulties getting the reflections and tinted glass. I'm having problems getting metal to look like metal.

Where am I going wrong? I've played with the specular and translucent aspects but can't seem to get it.

Help........ ;D

Sorry no one has responded to your queerie regarding reflections on object. I can't help you in that regard as I've been trying to do the same thing recently, without any success. Best I could manage using the reflection parameters was an inadequate milky look to my "metal ball". It might be a good idea to send Seth a pm asking him how he got the metallic reflection look to his metal ball in his "Balls and Stones" image:

Meanwhile I'll keep trying to produce something acceptable, that is worth sharing.

I hope I realise I don't exist before I apparently die.

I am working on the glass now. It is easy to get an object to vanish...

I tried several settings using the default shader. I tried a reflective shader, with some small success. That is until the transparency goes below 0.7125.

Last thing I tried was a water shader. Reduce the roughness to zero. The transparency can be adjusted. The Decay Distance seems to be the key here. This needs to be set at the objects scale size. The reflectivity can be set also.
This seems to be the solution, at least until the new object render engine is released. Apparently the current render engine uses a z buffer for transparency. From the bits I've read in various posts, the next object render engine will be full ray-traced.

P.S. - Please don't think we were not answering you. This is a very difficult subject to implement.

for metallic objects, pipe the default shader through the reflective shader - there you will get real reflections. Highly reflective materials need a pretty high index of refraction, I think you can go above 15 in some cases

Walli, those are pretty much the same settings I tried On the bottom image. I did not get any type of result like that. I'll post what I was able to manage.

I didn´t try on imported object so far (well, I did a very long time and it worked as far as I can remember), I used the built in sphere object. Hopefully this doesn´t make a difference.

Marlin

Thanks for the info I'll give it a try.

;D ;D

Here is what rendered out using Walli's settings. I am using Version 2.0 (Build 2.0.3.1) I added the clouds so there was something to be seen through the image.

Well, I wasn't even aware that the transparency worked correctly in the reflective shader yet. I'd been still using my own transparency shader(an edited water shader) up until now, I'll give the reflective shader a go again now, though. Cheers, Walli! :)

Looks like you still have the water shader hooked in here.

Marlin

Here's what I got....



I'm still having problems with the complex objects...A crosswing fighter from ShareGC. either opaque or transparent. What about a glass shader that is for objects that have multiple surfaces to work?

When you right click on the shader and add reflection it will jump to the default shader (material) reflection tab, don't let that fool you.
Jump your IOR up, not reflection.
