    My renderings

    Have been working with Revit for a while now and never really was allowed to spend time to render the designs. Boss said I could not get pretty images like other people can in Sketchup (??!!) so I thought I'd give it a go in my own time. It is not done yet, but I think this is already pretty nice for the hours I put into it (around 8 or so) considering I had to find out about everything by trial and error.

    Any pointers are appreciated.

    Pretty good going for a first go at an interior shot!

    I don't think it unfair to say the ceiling tile material leaves a lot to be desired; experiment with the image size and bump to reduce the visual-clunkiness of the faux-panel-lines.

    Your lights are a little "flat" also - and look to be made with lenses set to a light emitting material, rather than glass with a light source behind - which in itself has helped reduce "spots" on the otherwise well-judged reflective settings of your flooring &wall materials - but doesn't really aid with casting light as it might look in reality - but would add a more dynamic appearance (light/shade/dark) to the image overall - which at the moment has a tonal "flatness" akin, if not wholly the result of, the light sources.

    Some might play with adding a studio/area light into the mix, perhaps behind the camera, to "lift" the scene - but before doing that (it is, after all a viz. hack you want to avoid if being honest about what that room might look/feel like) I'd experiment with your exposure settings post-render (either in Revit or a suitable image-editor)

    I second Snowy's remarks. I also really like the window at the back of the scene. The reflection in it adds a lot.

    also:

    What size & quality did you render at? It looks like there is some compression artifacts, especially at the ceiling. Finding the balance between render quality and speed is a never ending exercise...

    I think a larger image size will help with the moire on the ceiling panels over the computers as well.

    What is your flooring? The floor looks like a sheet vinyl, if it is a wood plank system or tile system you should look into your map and add or adjust the bump map. [CG Textures] - Textures for 3D, graphic design and Photoshop! is a good starting point for textures, although finding a good wood floor texture can be a royal pain. You might also increase the size of the map. It isn't "correct" but it will look cleaner and the bump will display a little better.

    Thanx for the reply and I 100% agree with you on the ceiling panels, they are still pretty ugly and something I will look into. There will be more light in between the beam ceiling, that will light stuff up a bit in the middle and I already made the monitors glow a bit.

    You are right about the light and those being made with a light source and light emitting materials to show the glowy bits, I'll see what I can do there.

    The window at the back of the scene is actually a glass office wall, where I have put some lights for the next render which should show a little more of whats inside.

    The floor is indeed a wood floor and made with the OOTB revit wood flooring texture, I will have to look into that I guess. I also don't really have any idea yet on how to raise the image size of the render, using the screen resolution until now, also something I have to look into.

    Seems my PC at home is not as fast in making renderings as the one at the office, so I will do a bit more tweaking next week after work hours

    I actually like it the way it is

    Use the Size Crop button. Select the crop region and the Size Crop button will pop up.

    Question: When putting glass in front of my light sources in the light fixture models, it does look nice, but the light does not give nearly as much light as it does when I do what I did before (light source below a light emitting piece of 'glass'). Am I missing something, or do I have to add a second light source to the light fixture ?

    Good rendering for a first attempt, and some good comments on it so far. As has been mentioned, the scene is pretty dimly lit. Play around with the exposure a bit; just be careful not to wash out the brighter spots. Boosting the ambient lighting and ambient shadows helps even out the lighting. I'd also consider putting something like a task light on each desk. As for the ceiling, you might consider modifying or creating your own pattern. Armstrong.com, for example, has images of their ceiling tiles you can poach the texture from.

    I'm interested to see your next attempt at this rendering and hear about the improvements you made.

    Thanx. Was a bit busy at the office the last few weeks (which is good) but had little time playing around with this and my PC at home does not like rendering to much. I did however try the AutoDesk 360 cloud rendering and it does look OK as you can see in the attached image.

    A few minor design changes since my last image and a couple improvements (like the ceiling). I even have the sprinkler head in there now (might want to turn those off for renderings)

    The two things that jump out right away:

    The green wall to the back-right is LOUD. Could be because of cloud rendering instead of local.
    The floor still looks like a sheet good and not a plank. Could also be due to cloud rendering.

    The other item I noticed is the light & louver layout in the ACP ceiling seems really heavy towards the back. The spacing seems off. If that is correct then don't worry too much about it but pulling them closer to the front of the scene might help a little.

    As does the wall at the back left. It's reflecting across the ceiling and onto the opposite wall.

    It looks like he found a better image map, but it does need some bump.

    I agree.

    Other comments I have: I feel there are two main things that bring a rendering to life. The first is the technical quality: lighting, materials, resolution, etc. The other part is the content that fills the space. There has to be a balance between the two, but adding content like fire sprinklers and water coolers helps draw some attention away from pattern repetition, sharp edges on everything, etc. It also helps fill in the blanks for the viewer. Same concept as staging a home; you want to give the sense that you're looking at a functioning work space.
