First render! tips?

basjuh

Hi,

I just made my first sketchup drawing and render.
I did the render with IRender nxt.
First the sketchup drawing

The first render i did with exterior settings, and some minor changes.

Second one i did with high dynamic

My question is how can i make them look better, because they are way to light i think. or am i wrong i dont know.
Well can you guys give me some tips?

Thanks
Bas

I'd say that first step would be materials.
CGTextures and Arroway both is good start locations to find better textures. There are many object in your scene with just plain colour. Have a look out for good textures to replace them.
And the glass material needs some changes. Glass materials are 100% transparent (usually unless you have a slight ting) and the only thing you see is the reflection. I don't know how IRender nxt works - so someone else will have to fill in who one does that in the application.

Two quick tips:

There is a "brightness" slider bar above the rendering itself. If the image seems too "light", slide the brightness bar to the left.
"High Dynamic" lighting produces subtle lighting effects by filtering light in from the sun and sky through an invisible forest. Your images shows individual shadows from the filtered light. Give the drawing more rendering passes and the shadows will blend together to create the desired subtle lighting effects. (Some people let things "cook" all night to get the final rendering.)

I agree with Thom, you need to work on your textures. 2 things that will make a good render or ruin it are details and textures. Get those right and you will be on your way.

There is not a "perfect render" button that will make everything right. It takes time and effort.

Let's just talk about the masonry. That texture, if you decide to keep it, seems to be out of scale in reference to the human figure, and the jambs at the windows are a different scale and texture from the face brick? If that were American modular brick, each unit would be nominal 2" x 4" x 8" (actual 2 1/4 x 3 5/8 x 7 5/8, with 3/8" mortar joints.)
However, if you intend that the masonry units be larger, then you may want to use a different texture more representative of, say, brownstone units, or cut stone.

Yeah your right, i did this on purpose though. i thought the rendering time would be shorter. And i didnt see that the textures on the inside were different until i made the renders, so i changed that already. i changed my passes to 40 what is better.
I used some different textures from CGtextures, but this one is the best compared to the real building. I will try some others.

Thanks for the tips

Glass on Greenhouse

Glass can get tricky. Some SketchUp glass materials have colors other than white. You are better to change them to white, because natural reflection on glass will add the color.

Similarly, you may need to make the glass more transparent. SketchUp's OpenGL renderer only applies transparency to light coming through the glass. Reflection on glass can make it seem less transparent.

And, IRender nXt processes glass differently depending on whether you used two faces in SketchUp to draw each pane or just one. If you used two faces paer pane, then you should mark the glass as "Thick". (Right click on the glass n SketchUp, select edit material, and check the "think" checkbox)
