Melhorando a água do P3Dv2.1

Mensagem por virtualroutes em Qui 06 Mar 2014, 20:10

Estava pesquisando como melhorar a aparência das águas dos mares na versão 2.1 e consegui descobrir como deixar as ondas (com Dx11 e tesselation ativados) bem melhores. Porém não sei como anexar esse arquivo aqui para que todos possam testar, é um arquivo com 546 linhas achei muito grande para copiar e colar num post, aguardo orientações de como compartilhar isso com todos.

Olá virtualroutes, você pode procurar um botão na barra de ferramentas chamado "Spoiler", veja a imagem abaixo.

Ao clicar você pode colocar um título e depois irá aparecer o código ["spoiler][/spoiler"], entre um e o outro você coloca o texto que deseja postar.

Obrigado pela dica!

Bom, a edição que sugiro fazer fará com que as ondas pareçam bem mais realistas, com qualquer intensidade de vento, mesmo com ventos fortes o mar não vai parecer estar em ebulição.

Na pasta ..\Lockheed Martin\Prepar3D v2\3rd Party\TritonResources tem o arquivo Triton.config que deve ser feito um backup, caso deseje voltar ao original.

Abaixo segue o novo Triton.config com as alterações, para funcionar o tesselation deve estar ativado.

Opcionalmente, pode-se baixar o SDK do triton http://sundog-soft.com/sds/features/ocean-and-water-rendering-with-triton/
Após instalar, na pasta Resources, podem copiar e substituir os arquivos do SDK, mas apenas os mais recentes!

Espero que gostem, estou usando com o REX mas tem algumas configurações das ondas que não ficam muito legais, então testem com a texture default ou outra menos brilhosa do REX mesmo.

Triton.config:
# Triton's configuration file - this is read at initialization time, so restart Triton
