I don't know if you already solved your problem with craters and holes. 
The friends already gave some instructions, I will give an idea, use a lot that in my works. 
 
Choose a mountain, turn her for the summit to be down aligning her/it to the ground, go up a little and later transform her/it in negative. 
Contain the mountain and the ground; 
You will have a hole... your size and depth will depend on the size and of the height of the mountain.

Gratefulness for the votes.
Although to only have 3 competitors, I was very happy for having been the chosen one.
I am thinking about the next subject.
Thanks.

How long have you used Bryce?: 
2 years 

What kind of art do you create usually?: 
Landscape, Abstract, Jewels, SCIFI, Fantasizes, Models,.... 

Would you ever move over to Vue?: 
 I use VUE regularly for studies and when I like the result I publish in my gallery; but if Bryce didn't come with new resources, VUE can be my second brush.  

What is your most favourite Bryce art that you have done and why? 
I am not a lot of friend of landscapes, I prefer my models or even working with other artists' models. The textures, colors, and illumination are much more realistic. Perhaps for not having a lot of technique in landscapes or even for the deficiency of Bryce in realism.

Periodically they appear comments than Bryce was able to or he/she should have. 
I think eat that subject it always comes back, little it was done of concrete by that. 
We were able to, as he/she suggested Death_at_Midnight, to create a list of what would like to see in Bryce, to send to who will really be able to change. 
Lately I am making several studies with VUE and I admit that I am liking a lot, but I would not like to leave Bryce. 
Not to do really a new version with changes significant, Bryce will be passed for many. 
Excuse me for the mistakes, I had to use a translator.

Hi Burpee. 
Thank you for the congratulations and for having placed me in the 3DCommune (you were who gave me the information). It was a beautiful surprise, and you were who informed me. 
With relationship to my challenge, I hope the community participates. 
You are well coming. 
Hugs..

Congratulations Death_at_Midnight, Drawbridgep, SavantNoir and the all the participants of Bryce Challenge.

!!!!! Challenge is on as of right now and Deadline will be on March 28th, 10p.m.    (Renderosity Server Time)  [no exceptions] !!!!!

If the period finished, because the sending is still possible?

Be permitted an observation: 
Hundreds of artists that use Bryce exist, few they send your works. 
Or the challenge forest same Bryce, or he/she is not having a lot of importance. 
The Theme is excellent. 
 
Instead of we be discussing the quality of Bryce and comparing with other tools, because we didn't address our efforts in the competition? 
We will make Bryce to work at the most, our imagination can help...  
Bryce, Vue, Carrara, Poser, Terragem..... they are great tools.... but excellent same they are the artists that use them.... 
I would like to see a challenge in Pure Bryce.... the challenge would be much more gratifying.... 
 
Art is to be enjoyed, the quality is relative.... 
Excuse for the relief.

Rotative banner.
Brilliant idea...
