I WANTED SPARKLES.

Not the Hewitt boy's Sparkles but proper ones for the birthday video mark sevenish.
 This Blendering is becoming obsessive, not unhealthy so as I went for a haircut and still admired the hair cutter. Drop dead gorgeous she is and reasonable at six pounds a trim plus a tip for being quick with the scissors and comely.
I decided to do another birthday video. I wanted multicoloured sparkles. Not asking a lot but 2.8 has forsaken groups. And Layers. We now have to use collections. These Collections are better for instancing. (Your guess is as good as mine). They do work a bit like groups. Finding out what to click when and where is a real pain but endlessly entertaining.

I have had a couple of days fighting software. Adobe has a great selection tool in the eraser. It will separate a horses hair on it's mane or tail from the background, assuming the background has some contrast it doesn't need much but you do have to take passes with adjustments in between them. It  is no good shooting in JPEG through a phone or worse still a bridge camera. One needs massive files to produce a tidy result. The problem is setting it up to do it. Anyone with PS6 wants to know just ask; I'll do a tutorial on the hidden nightmare. I began to see the attraction of one click Apps with a slider or two.

The following video is my attempt at showing how to use collections to group multiple objects as particles in Blender 2.8. There are a few interesting and colourful bits for the majority who won't succumb to the free entertainment this software provides and I finish off with my latest project which is getting object transparency using the EEVEE render engine. A right pain in the bum it is too but I'm almost there.
 I have rehearsed this a dozen times over an hour or so but still cuckoo on the final screen grab. I'd be a terrible actor. I can't learn my wurds. My fingers press stupid. Special needs I am.


That's all for now.

SUCCESSFUL FUN.

Yesterday my brain turned to mush but when I woke this morning just a few clicks sorted the problem. No special needs for me. This is done start to finish in Blender 2.8. I'm not an artist so that side of things could do with improvement. The video rendered at between six and eight seconds a frame using EEVEE. I suspect that using cycles the time would be measured in minutes a frame. I'm a happy clicker.
That's all for now.

FUN.

Life can be a little depressing at times. I am struggling to master Blender 2.8 but I am making progress. It does crash now and again. Not that often unless I confuse it.
 It reminds me of the time years ago when I went to work in France, I spoke all day in French to the best of my ability. After work we used to go for a beer and after I had got used to their custom of two tiny glasses and not our custom of three or four pints, it was grand.....Almost....I can speak languages but can't write them. This is how the conversation went. After the first round.
Rigger. " questque tu prend?"
Me.       " Un autre si vous plait."
Rigger. "Que d├ęsire?"
Me.      "Uno cerveza por favour?"
Rigger. " AAH.... Le meme chose......Graci.
So language is learnt. Everything else for that matter.
A week later we entered the same cafe and It was my turn to get the first round. I asked what they would like, Keska eel prendez. They said, Cinq, something different to biers but it was Saturday lunch time so I thought it was a special drink they had taught me. I recited it twice and in I went. The lassy didn't bat an eye when I conveyed their wishes but when they followed me she flew from behind the bar and thrashed them with a wet towel. I did ask what they thought she was capable of giving me five of and more to the point could I survive it. They were all in convulsions so I never did find out. My French wasn't up to it. So language is learnt.
School should be for the three Rs. No good asking a teacher to teach this 3D malarkey. No good asking me but I have had a request or five and I don't bull shit. I can sort simple stuff for folk. Teachers seem to demean pupils to cover their own inadequacies. (that was a hard wurd; Thank the Google for spell chucker)
Blender 2.8 is a lot like this. I went back to 2.79 and was struggling. The new interface is so much more intuitive that I am in awe of the work and effort involved. It will take ages for the manual to catch up so I am doing what I always do; click on stuff, pray and try and remember what worked and what didn't.
This morning I downloaded a new Beta version and low and behold it gets better. Silly things like fonts are now easily legible in the font viewer, the bevel tool is silky smooth, the video editor accepts image sequences without any hassle. If you drag and drop HDRIs then it is a disaster zone that takes twenty minutes with Mapping to sort...Half sort.....I can get it something like. If you load them sensibly through the node they work fine.  It will get sorted. I am on my third iteration of 2.8 Beta and if you see anything below I've done summat.
I definitely did summat.
I got both screens full to overflowing with PNG images. Bastard! I saved them to a file on my desktop as is my wont but it ignored the file bit. Not only that it ignored my sparkles! See no sparkles. Bastard EEVEE and bastard Blender.
You aren't supposed to see the cone bit and the lighting needs a shove. EEVEE is good but it will Take me an hour or several to work out what to push where. I am pushing it as little as possible the particles are this shaped.

I use the funny thing on the right as a particle, it has two fewer vertices than a cube and two more faces to react with light. It's only four days to her birthday, Help.
That's all.
