Karl’s Art Sketchy

@brohmyr Hey thanks Buddy! It does get quite technical at times.

I was on holidays most of last week, and got a little momentum loss, There was some drawings that are a bit out of context for now.

Just having a bit of fun making a package for Kraid!

This is with Rhino3d, Zbrush, Solidworks (fillets and shelling), and Photoshop.

There was also a little time to experiment with reflections and shadow color. Roughly. I was trying to absorb some of Marco Bucci's youtube videos on Ambient Occlusion and shadow colour.

Had a little time to do a life study. I'm not completely sure how to do brushed metal.

Time to start doing some more original work again to make some use of the studies. Looking at doing another bike based on similarities to this older concept.

The biggest difference may be that it will start with drawings rather than a model which gets built and modified. Which can be a bit driven by the program.

Some work continuing on the bike. I think this might challenge the use of reference a fair bit, as the previous one had no direct references. I prefer the direction of the one second from the top.

There was some time to do some Master studies as well. After some practice with colour, and refreshing observation skills. And a look at how things can be handled.
The first one after John Singer sergeant was pretty tough, and I feel originally was warmer and more greyer than Perceived.

This next one was an experiment with shapes, and doing everything with hard edges (polygon selection tool). With a final diffuse and lighting effect.

I was keen to do a cezanne copy, I think maybe too quick in early stages.

And finally A JMW Turner Study. Something is working about using opaque colour for this.

A side project, This model is roughly 15 years old now, and i was thinking originally the paintover might be a bit quicker to go to base matte and build things up... 5 hours of path masks later with no end nearby it was getting super complicated keeping track. So decided to keep the red paint and add now more informed reflections and fresnel.

Rhino

The original had issues with clean marks, the wheels are not really worth the time painting. and was a bit flat in places.

Things got stuck here, or at least pretty slow before scrapping.

Been a bit of a weird couple of weeks. I am studying Horticulture at the same time as drawing this year, and the two seem to clash with each other. Time wise. And one being on the mind while doing the other. There is only a couple of months or so left for Hort though.

Working more on Colour, Materials and Lighting. There is what feels like a useful course for this point on Domestika by Sam Smith. Which does explain some of the colour shifts in the master studies. I was feeling a bit like the Scott Robertson resources are strongest for either Reflective or Matte and describing form and it would be worth exploring a few other resources.
I was up early following along the Lightbox Expo demos, by Sam Neilson, and Nathan Fowkes. I might come back to the Sam Neilson demo after the Sam Smith course, mostly due to the pace.

I've been gone for a little while. It was a bit bananas with work stretching sometimes to nearly 11-12 hour days later last year. And I had to prioritize finishing the Horticulture course, which has been pretty useful. All better now, So I am hoping to continue where things left off.

I continued with Sam Smiths Assignments. And am putting together some things with Rhino and Zbrush.
I think Form does help with the Lighting course but they complement each other.

Sam Smith Sunny Day Lighting Part 1 and 2

I have started importing rhino models into Zbrush, rather than the other way. Seems okay with high poly counts. When i started with Rhino 3 long ago the computer would often crash with high polys. Rhino 7 is a bit friendlier. I think the Zbrush model may be much quicker and neater to build with primitives especially spheres, though have committed to a rough base long ago with the experience I had then.

Continued exercises. Starry night, Cloudy day, coloured lighting in a room and sunny room lit from outside.
The sunny room seems to be the hardest. Dealing with bounce light and defining the volumes. And being subtle!

Thanks cedricgo! There is a few more assignments to go.

This snowy one I painted in some white snow on the local color layer. It was a self chosen scenario. it is harder to know if it works with these, without instruction to follow. Snow does have properties that are not quite matte, that may be answered in the translucency exercise.

I played with reflections a bit more with the excavator. I was thinking of lighting studies with this, though it may be better to get smaller scenarios/models right before bigger ones like this.

Some translucency and reflections were added to the Sunny scene, and the Room under coloured light assignment.
Not sure if these are completely right, as the tutorial explains how the local colour changes to the light, though not necessarily the reflections. I guess the strategies with the cars may work... though a simpler object/s may be a better choice.

Other than these excercises, I'm getting a Model towards rendering and painting stage. There has been some success sharing a .Obj file with zbrush using high polygon (with quad remesh) exports from Rhino.
Getting the programs to help each other.
I have found a way to fix wonky but more geometric bits with the Zbrush Ridley model by experimenting on a hatchling, at a later date.
Zbrush seems to be great at adding missing texture and bumps and smoothing, with less rigidity than Rhino3d so far.

The year has gotten away quite quickly, Merry Christmas everyone.

Created a scene using zbrush for a cavern, and a few overlays to use or discard lighting and reflections in photoshop.
