  • My texture journey continues.....I was never happy with the black/white mask I had created for the tiny ship windows that I was getting from JSP.  Not that JSP is a bad tool, it isn't.  It's actually a must have in my opinion.  But while there is some control of the random patterns it creates by creating vertical or horizontal sections, it places those sections randomly across the image.

     

    I was looking for something unique in that I wanted to lights to reflect floor levels in the space station.  They needed to line up and be restricted to individual rows of pixels in the final image.  Not easy to do with a random texture generator.   

     

    So what I did was to create a plane that was roughly 184 x 324 polygon is size.  I then textured it completely black and colored the 4 polygons in each corner completely red.  I placed a camera above the exact center of the plane and had it facing it straight down.  I set the render size to the same ratio as the number of polygon and did a few quick renders while repositioning the camera to insure that the red corners were exactly at the corners of the rendered image. 

     

    Next was to go in and do a few loop selections to select the floor levels I was looking for and then remove polygons from each of those selections to get the randomness that I was looking for.  I will admit that this part was tedious.  When done, I painted the finished selections with a flat white material to generate the black/white mask of windows I was looking for.    Once rendered, I then painted the red alignment squares in the corners black. The finished image is below:

    And this is how it makes the windows appear in the final render.  It definitely sells the concept of floors within the space station.

    Well worth the hassle though - that is one damn fine luminance map you got there :)

    Thank you!   From you that is high praise!

     

     One thing for sure....if I don't get what I want, I keep trying.  Given that this is a hobby, I can only eek out about 4 hours a week by the time the rest of work and life is taken care of.  So those little dots represent about 2 weeks of time (or 8 hours of experimentation).

     

    Today is a rather unique day....I killed back hauling dirt yesterday  (dead lifted a 150 to 200 lb sack over my shoulder.....I thought I could do it...I did...but I paid a price).  So I hooked up a heating pad to my office chair and have been working on C4D all day.  I am now working on the space dock doors.  Three attempts today so far.  Just not happy with it. I am using a design by Robert Wilde for inspiration.   The inner door break on his design  has some pretty neat geometry but I am struggling with the topological flow.   To many cuts and then he indents and bevels the inner door "C" glow.  If not done right, you get a lot of crappy triangles and phong errors.   Here is what I have so far:

    But this is what I am going for:

  • The Dock doors start to take shape.....finally getting something that I am happy with.

    At this rate, I should be done with this project by next Christmas...but I am having a blast and looking forward to every challenge and utter frustration along the way.

    Dammit, I've been itching to help you out with those loading bay doors, but clients have been keeping me a bit nose-to-the-grindstone recently, so I haven't had much time to experiment on your behalf. But I did wonder if one viable approach wouldn't be making them in 3 vertical sections (top and bottom plates and the middle bits) so that your edge loops could be independent of each other. Just a thought - I see you've pretty much sorted them anyway :)

     

    Something else has caught my eye if you are interested...

     

    Those little luminant port-holes there - they are very 'on the surface' at the moment. What about using an inverse of the luminance map (possibly minutely blurred) to subtly bump those windows into the mainframe ever-so-slightly ? That might add another little contributory factor towards the perceived 'bigness'... what do you think ?

    If I have your attention, I must be doing something right!  Good suggestion on the doors --- I never even considered that approach...you almost make me want to redo them one more time.

     

    Relative to the port holes--- Another excellent suggestion.  Yes...they do look a bit floaty and that did bother me a bit.  I was just happy to finally get a pattern that made sense, so I was going to live with it.  But I am eager to try out your suggestion … so I will get it to it tonight after work.  Normally, I hate bump maps in non-organic models.  They just don't read well to me.  Normal maps tend to be better.   Let me try both (I think there is a H2N shader that converts any image to a normal map).  If normal maps don't work out as well, then blur in the bump map will probably take a bit of the curse off a bump map - that and the new parallax bump capability in C4D.

     

    Thanks again....in one post, you gave me two suggestions that in my wildest imagination I never would have considered!!!

    Yep, you can certainly go the Normal channel route instead, although the amount of bump you want is SO minute relative to the scene scale, in this instance bump might just be enough. Easy enough to try both I guess ! 

     

    Do post what happens if you turn parallax on ! ;)

    Okay....the results are in and while encouraging, they are a bit unexpected.

     

    Below is when using the bump map.  As anticipated, the depression around each light is a bit soft.  So while it grounds the lights to the hull in a distance, should you get close, this could be a problem:

    Now, when using a normal map something weird happens.  If you notice, the actual depression with a normal map is crisply defined -- which is why I favor them for non-organic models.  But notice that the lights appear off...almost out of sync with the luminance map for the lights.

    Let me keep working on this....the results are encouraging, but there are more things I need to try.

  • Okay...this is weird.  All I did was shut off the normal channel and turn it back on again, and the floating windows disappeared.

     

    Interesting.

    I zoomed back a bit and you can really tell now that the lights seem a bit more connected to the hull.  Just compare the lights at the bottom of the image where the normal map is applied to those at the top where the are not applied.

    Great suggestion!!!

  • The inner core starts to take shape.  Lots to do as I just roughed out the shape and literally slapped a texture on it.  There is actually a ton of modeling on the inner core more so than on the rest of the structure.    I could easily spend 40 hours on the inside alone....which for me is about 10 weeks.  Honestly, I wish I was retired so I could do this full time.

    Following this thread with much interest as i once tackled this project long ago using Imagine  and later on lightwave,so know full well what a pain it can be ;-D at least you have semi decent references nowadays i had blurry vhs tape aieeeeeee  its all looking fantastic :-D
