Learning to render with Twilight Hobby
-
Sorry I did not see your thread. I would have posted in that one. Maybe someone can move this. I am going to look at some of the things in that thread to learn more about how to use Twilight.
In the one I posted, I think the metal is too shiny so I need to back it down a little. Again all part of the learning process.
-
No Dave, have your own thread, that's what it is all about. I gave you that link simply to give you the info all together rather than trying to think it all up again.

OK - Will keep it here and use it to show my progress........
There is some valuable info in your thread. Thanks for the reference.

Something to remember as you go forward everything about rendering is a dark art. The smallest change in settings can change the result beyond comprehension. Like everything else in the scientific world, experimentation leads to repeatable result and a theory as to why it works, that can be rewritten many times.
Here for example the very same scene colours/material environment unchanged. The only difference, one is 04 Easy preset Medium and the other is 09 Interior Progressive.
-
Boy @Box, that is some really interesting results. Especially considering that you made no change to the materials.
Making some more progress.....but other things I need to learn for next step.
Right now I am trying to create something to use as a background for the renders but struggling a little. Are you just using a color background or do you have an image and then using lights?
I wish the documentation was a little better or at least in terms that a pure novice like me could understand. When I look at some of the links from your thread, the stuff looks great but trying to understand and apply it is turning into a challenge for me. I am feeling a daft right now.
I tried one of the tutorials I saw on the Twilight site (the one with the wood block roller coaster) and it came out pretty good but there was one part of the video where they showed beveling and I could not get the same options when I tried it. Will sort that out later.....not important for me right now.
-
Some more experimenting:
Not sure how I like this one compared to some of the others........the metal is more realistic looking but I am not happy with the background.Now for a different question:
I tried to create a background skp file for my equipment renders but it is not coming out at all like I expected. I obviously do not have something set up correctly in SketchUp.
I had tried to make everything a lite gray. It looks darker than I want and the back face is really bright. What can I do to get this more subtle? I wanted a light background without sharp edges but something that would catch shadows and I could get a reflection of the equipment.I feel like I am missing something very elementary and in some cases maybe even going backwards.
-
A couple of things that might help.
Grab the HDRI studio pack from the store and use one of those as your light source without any sun. So in the environment tab set background to Hemispherical sky and browse for a background image to one of the HDRI you downloaded. Each one will give a different result.
Set the material of your background form to plastic satin or shiny.
This should give you a better lighting structure to play with the other elements.
The critical thing is to create something for the shiny metal to reflect, the Studio HDRs give you this.
You may want your backdrop form to be larger and even a bowl shape with a flat part in the center to sit things on. Different studio layouts give different results. What is outside the opening in your backdrop and where it is will affect how your reflections work.
Remember, The sun isn't great for product renders, you really need to create your own lighting and environment, that can include throwing in other geometry out of camera view to give you something to reflect. With a plain surround all you get is a flat reflection. Look at a flat white wall in a mirror and what do you see? -
Thanks for the feedback Box. I switched over to using the Light here is my first render.
This is much closer to what I want. The reflection I was talking about before was being able to see the equipment reflected in the floor.
Lot more experimenting/learning needed but I feel like I am headed in a better direction.

Would you be willing to send me that SketchUp model? I'll try rendering it to see what I can get.

Here is the model..............
IP Stripper-inside.skp
Yes, I need to go read some more of the tutorials about applying lights.However, I had to try one more little wrinkle first..........
-
I didn't spend much time on this and I only set up a material for the large diameter pipes and the blue thing. It could be better but I just wanted to get a quick render out. What do you think?
-
Dave, I like this better. What renderer are you using? The sections above the blue blower are blue also. I like the color of the metal better as well. Maybe just a little more hint of silver but it has a better degree of shine than what I am coming up with.
-
Here's a quick one.
I've changed no materials, so there is plenty of scope to play with those.
As I described above I used a flat bottom bowl as the background, turned off the sun, set it to hemispheric sky and added number one hdr from the sketchucation studio pack, reduced the brightness to 3, deleted your light and your box and rendered on easy medium for less than 2 minutes.
If you create a good environment you have good base to start editing your materials.

This was done in Kerkythea.

Oops! Since that entire horizontal pipe is all connected geometry, I painted it all the same.

That metal is from a preset. I didn't bother to edit it but I could have made it look more polished. The background is the default front face color.

Sorry no Twillight presently under hands!
So Simlab
Then Fotor
Then Fotosketcher + Fotor
-
Nice to see a clear system of feedback and real progression here! Keep it up!

You guys are all making me feel bad. Why am I having so much trouble learning how to do this?
@Box, @Dave R, & @Pilou You are each showing me some really good results. I do not seem to be getting the hang of things. I am trying to learn one step at a time but seem to be going backwards. Box, in particular, I really like the reflection of the equipment in the floor. Pilou, your colors in your first render really stand out to me and I like the floor tile.
I have been using Twilight because it is free. I was trying to apply one of their lights but I have to admit something about the 3 click process is not going well for me. Do not fully understand where I am going wrong.

Dave,
Did you use a edge overlay in the render? Nice job. I think the metal as he says is nice, because the other metal looks too perfectly reflective to be realistic.
