Finished cottage and finished module!

Today I finished my last piece of this work being the cottage. I'm actually really happy with how it came out. The The whole thing looks pretty nice in my opinion but there are a few things I would change if I did it again. The normal maps I found a little bit buggy and couldn't find a way to fix them but in the end they came out okay once they had a diffuse on too along with a bit of tweaking. The roof tiling was surprisingly easy and worked first time. The incandescence maps were easy to make yet I don't think I made them brilliantly but then that's something I can learn in the future. Overall I'm very happy with this piece of work and think that this whole module has taught me a lot and will guide me into much of what I will be researching this summer in my own time.

Marmoset alien heads

These are my 3 marmoset renders of the low polygon alien head. I'm really happy with how it came out and am looking forward to moving forward with more ZBrush work in the future.

Today I finished all work to do with the alien head paint over. This involved baking all the details and colour values from the high poly head (in the millions of polygons) to the low poly head in Maya (6,000 polygons). Despite the massive polygon difference, their isn't too much difference when you look at the 2 heads. They both look great and I'm really happy with my work. I created a number of maps for the head but most were done through just using the low and high poly meshes, only the specular required me to paint it myself. The UV'ing of the low poly head was quite difficult but with the help of my friend and lecturer this went quite smoothly and ended up giving me a good result.

Overall I really enjoyed this part of the module. It went smoothly, the work I created looks good and it didn't even take that long. I learnt how to do several basic painting techniques in ZBrush which will be very useful in future. I also learnt about how to bake out of ZBrush onto a low poly version of the model. It also helped me a little with imagination (don't laugh, it's true!) as it got me thinking about using a wider spread of things for textures. On this alien head alone I used jellyfish, burnt flesh, rotten flesh, several types of bone, gecko eyes, lizard scales and raw meat pictures to create his final image. This was a great exercise.

Next I plan to get some nice Marmoset renders of the low poly head before moving onto completing the cottage assignment before my final hand in on the 28th of April.

Finished face paint

I finished the paint over of my head today. I'm really happy with how it came out and found that Zbrush is actually a lot of fun whilst having a lot of functionality. I ended up adding some new ideas to my paint over but kept to the original plan for the most part. I added a lot of burnt skin to him as it just ended up working really well. Below are some of the textures I used for Spotlight painting. Next I need to UV map the head and get it onto a low poly version eventually.

Lizard Skin

I used this along with another non-gradient version for the base skin colour and texture of the head. It is a simple image with a gradient on the colour layer style. 

Bone

This was my first bone texture for the teeth and neck bone. This is simply an image with a multiply layer and duplicated it all using the overlay style.

Bone2

This was my second bone texture, used for the aliens crown. I used a colour overlay and my previous version in combination with a new image to create this.

Gums

This is literally a slab of meat I used for the gums. I then edited it in Zbrush.

Jellyfish 

This is a beached jellyfish which I used for the warty areas on the side of the aliens head. I added a red colour overlay, used levels to get rid of some highlights and added detail with the brush tool.

Rotting Flesh

This is an an image of a plastic bag that was heated up a lot. I used a multiply layer, colour layer and overlay to make this. 

Zbrush progress

Since this morning I have made quite a bit of progress on my final version of the Zbrush sculpt. The first thing I did was create the eyes as I felt most confident doing these. They are very simple gecko eyes that I turned sideways and then added a little detail to. This was done through Spotlight.

Next I created the detail for the neck parts. I decided on a warm colour scheme for the alien, much like certain breeds of gecko, and so wanted to feature both mechanical colours and some natural colour in there. The end result was 2 shades of grey, a browny orange area and some yellow lights. I'm very happy with how these turned out.

I did the teeth after that. I struggled to get some teeth that I liked at first as I was being to gentle with my colours and contrast. In the end I used a bone texture in spotlight. Afterwards I went through adding darkening, variation and a few lighter scratched areas. 

After this I finally blocked out my final colour scheme. It features mainly yellow, more bone texture and some orange in areas such as under the chin and some stripes along it's back. I also have made the glands a quite deep red, trying to add some variation to the model.

Zbrush - First impressions, colour schemes and experimentation

Today I started learning how to use Zbrush for one of my hand ins for this module. Overall, whilst enjoyable, I find that it isn't user friendly in the slightest (at least for the newbies). I get lost in the software and struggle to figure out what is happening half the time. However, when it works it's a lot of fun and I can see some of the potential of the software. So far I've experimented with different ways of texturing, different brushes and some tools.

One of the most important things I need to work out now is what colour scheme I want to do. I've played with quite a few colour schemes so far yet not found any I really like. I tried playing with white and blue a fair bit as shown with the first picture below. I'm happy with it how it looks there yet I'm not sure it'll work with the head as whole but rather the detailed plates on his neck.

I did several tests with eyes. The first was done through ZAppLink which involved taking my angle into Photoshop, painting it, saving it and then it would automatically apply. This method will almost definitely be used in certain areas of the model such as the bulbous glands on the sides of his head as I think the method would be well suited to texturing them. 

Below is another method of texturing that I did using Spotlight. This involved taking a picture of something and using it as a stencil. It worked really well and came out nicely. I can see myself using this method for the eyes and possibly any other details I like, perhaps for some kind of scaly material across the head?

I have also thought of how to paint the other areas of him. The teeth I think will be painted by eye in Zbrush as they are relatively simple. The same could go for the metal plating. The skin itself is the part that worries me most as I don't yet have a solid idea of what to do for it however I'm sure I'll come up with something.

Finished door

I finished off my door today. This is the finished diffuse, normal and specular maps. The diffuse had just a bit more editing done to it since last time. The normal map was done quite easily too, using my previous map in combination with diffuse maps which I changed to normal maps which were then normalized and overlayed. The spec was just edited from the diffuse map and was done pretty easily.

Here are two maya renders of my door. 

And the two renders I did in Marmoset.
