@Mike Many thanks Mike. And I absolutely agree with Michael. No, I will increase the praise. That's phototealistic. :salute <3
@Support Like I said, a perfectionist. :lol: Awesome. This time, too, I couldn't resist doing a space nebula scene alongside the Atlantis scene. :D

Oh f..., the interior scene that I wanted to create as an example image. Sorry, I completely forgot about that. :oops: I will create it tomorrow. Simply put, I want to recreate the scene I posted in February 2023 as “engineering department: main energy core”. But whenever I add some shine to the texture of the reactor hull, as in the original image, the texture is extremely shiny. Extremely much stronger than in the old image. Even if I only set shinines/reflection to 1.

@Okwa Did you use the fog with the nebula??? This is so good looking, whatever you've done, it looks and feel :o :o :o

ah, for the shine, do not use Reflections because it acts like a mirror at any angles. Shine is only reflective depending on angles. for example, a floor will reflect more when you look at it at a steep angle but will not reflect much at all straight on view.

Yes, I used fog for the nebula. Since I took both pictures one after the other, I noticed something curious. How the fog turns out depends on the size of the scene. It was impossible for me to get the fog in the Atlantis scene exactly the same as in the space scene. Even with exactly the same values, the Atlantis scene resulted in many small clouds. In Atlantis I could only achieve a complete wall of fog with small gaps (very small) and this little cloud you see here. But not this big cloud with big gaps like in the space scene. The only difference between the two scenes that I can see is the size of the camera area. The space scene is about 900x200m, the Atlantis scene is about 20000x30000m.
I want to try to make the camera section of the Atlantis scene smaller by reducing the size of the model. Let's see if my observation is correct or if I'm just crazy. :mrgreen:

I have also taken reflection out completely. But even with shine, the brightness is strong. I'll take the image today, only with shine. But maybe I'll just turn down the light. :lol: :salute

@Support Sometimes I learn quickly. Atlantis reduced to 5%, the camera section reduced again by the close-up, so that this scene is 1% of the size of the other scene. And the fog looks completely different. :D :lol:

@Support So that's the scene I meant. The first image is rendered with shining on 1, reflection 0. Maybe it's just me, but I think that's still pretty strong shine.
In the second picture, I went below 1 with the shine setting. I could have realized earlier that you can also set the value after the decimal point. :lol:

That was unexpected, to use the fog with the nebula, very clever of you :salute

Yes, it's size based. But for the Atlantis, bring the Density way down, like 7, the Contrast in the middle, the Horizontal at 900 or more and the Vertical 350 or more, this should give you big patches. But, 20000m? that's 20km !!??

ah, yes, you can right click the dial and type in your own value, including the decimals. When you drag the dial, you can hold down the Shift key to make it increment faster, or Ctrl for slower and Ctrl+Shift for very slow.

For the shine, another factor is your light. If the light is set to power=35 and you use the Area to make it brighter, the shine will remain at 35 (internally, that's 1). However, if you set the Power to make it brighter, the shine will be very strong according to that Power/35. so if power=420, the sine will be 420/35=12. I hope this makes sense?

Fog or Nebula, it's all just gas. So it's a logical use! :mrgreen:

I create the models in Sketchup in “real size”. So, at least according to Sketchup's measurement display. :lol: Atlanis is 7500 m in diameter, the other two city ships are just under 7000 m, which makes around 21 km. Add to that the distance between the ships. I think the width is probably closer to 30 km. And according to Raylectron, the camera is 21 km from the front edge of Atlantis. :lol:
I'll try out your values. :salute

Mmhh, that reminds me, I used the Auto function for the light setting, as always. And Raylectron set the power to 47, so I should really turn the light down. But I forgot. :oops: :D

I'll have to scale mine and do some tests see if I can adjust the fog to work just as well with these dsitances.

oh, and I've just updated the download link (same link), I added a vintage feature in the Special Effects. I don't think you'll use it but, I thought it might be useful one day.

I don't think 47 would make it that bright, but I may be wrong.

@Support
In image 1 I applied your suggested settings for the fog to Atlantis in original size.
Image 2 is the engineering department with reduced light power but greatly increased area adjustment, so that the “total area” display corresponds to the m² number of the model.
For image 3, I only reduced the power setting to 35, but for area adjustment I use the value set by the auto function.
Image 4 are my Nebulons in vintage style. :lol:

I'm not happy with the fog at that size. I've been trying to make it work, and it does, but at the expense of not working at low altitude!!!

If the shine it too much, you could add a bit of Diffuse, like 0,1

I like the Vintage look, it's really cool I think, but definitely not for a spaceship :lol:

Why should it necessarily work on this scale? How many of your customers will use Raylectron with such a large camera section? And if someone wants to render something in this size range, then he should strain his brain and simply reduce the size of the model. Then you'll get the effect you want. That's my opinion. Don't spoil the users of Raylectron too much. Otherwise they'll get greedy. :D

You see, I should use my brain more too. 0.1, of course I didn't think of that. :mrgreen:

Indeed :lol:

I guess you're right, but it still isn't perfect if I leave it that way :lol: But I'll listen to you and concentrate on better things :salute
